Allah does exist
A man went to a barbershop to have his hair cut and his beard trimmed. As the barber began to work, they began to have a good conversation. They talked about so many things and various subjects.

When they eventually touched on the subject of God, the barber said: "I
don't believe that God exists."

"Why do you say that?" asked the customer.

"Well, you just have to go out in the street to realize that God doesn't exist. Tell me, if God exists, would there be so many sick people? Would there be abandoned children? If God existed, there would be neither suffering nor pain. I can't imagine a loving a God who would allow all of these things."

The customer thought for a moment, but didn't respond because he didn't want to start an argument. The barber finished his job and the customer left the shop. Just after he left the barbershop, he saw a man in the street with long, stringy, dirty hair and an untrimmed beard. He looked dirty and unkempt.

Shia (Isaiah) - Isaiah and Hezekiah

Among the prophets between David and Zechariah is Isaiah (Shi'a) , Ibn Amoz (Amsiah). According to Muhammad Ibn Ishaaq, Isaiah appeared before Zechariah (Zakariah) and John the Baptist (Yahya) . He is among those who prophesied about Jesus (Isa) and Muhammad . The king during his time was called Hezekiah (Hazkia). He listened and was obedient to Isaiah in what he advised him to do and prohibit for the good of the state. Affairs took momentum among the Israelites. The king became sick with an infected foot. While he was sick, King Sennacherib (Sinharib) of Babylon advanced towards Jerusalem with sixty thousand men.

Shia (Isaiah) - Allah Grants More Life to Hezekiah

The people were greatly terrified. The King asked Isaiah: "What did Allah reveal to you regarding Sennacherib and his army?" He replied: "He has not yet revealed anything to me." Then the revelation came down for King Hezekiah to appoint a successor, as he wished, because his end was at hand. When Isaiah told him this, the king turned to the qibla (the direction faced in prayer); he prayed, glorified Allah, invoked Him, and wept. Weeping and invoking Allah the All-Powerful and Majestic with a sincere heart, trust and patience, he said: "0 Lord of lords, and God of gods! 0, Benevolent and Merciful One Whom neither sleep nor nodding can overpower, remember me for my deeds and my just judgment over the children of Israel; and all that was from You, and You know it better than I do, my open acts and my secrets are with You."

Shia (Isaiah) - Allah Destroys Hezekiah's Enemies

Then Allah sent death upon the army of Sennacherib. In the morning they were all corpses, except Sennacherib and five of his companions, among them Nebuchadnezzar (Bukhtanasar). The king of Israel immediately sent for them, put them in shackles and displayed them in the land for seventy days to spite and insult them. Every day each of them was fed a loaf of barley bread; after seventy days he confined them in prison.
Allah then revealed to Isaiah that the king should send them back to their country so that they might warn their people what would happen to them. When they returned, Sennacherib gathered his people and told them what had happened to them. The priests and magicians said to him: "We told you about their Lord and their prophets, but you did not listen to us. It is a nation which, with their God, nobody can overcome." So, Sennachub was afraid of Allah. He died seven years later.

Musa (Moses) - The Story of the Israelites and the Cow

The Pious Man and His Son Moses stayed among his people calling them to Allah. It seems their souls were uneasy in a way that the observant eye could not mistake. Their obstinacy and chattering about what has become known as "The Story of the Cow" was unwarranted. This topic did not need so many negotiations between Moses and the people, nor did it need all their bias.
It was said that among the children of Israel there lived a pious man. He was poor but very careful about how he earned his living; it had to be honestly earned. Everything that he did was done for the sake of Allah, never for selfish gain. On his deathbed his last words were: "0 Allah, I place my wife, my little son, and my only possession, a calf, in Your care." Strangely, he asked his wife to lead the calf to the forest and leave it there. He did this because he did not trust the children of Israel, for they were a selfish and greedy folk.

Musa (Moses) - The Israelites after Pharaoh's Defeat

The Moses's People Desire an Idol In spite of Pharaoh's death, he left a bad influence on the souls of the children of Israel. It was difficult for the years of oppression and intense humility to pass easily. He had made them accustomed to humbling themselves and submitting to someone other than Allah. He had so suppressed their souls and spoiled their nature that they began to torture Moses out of ignorance and obstinacy.

Musa (Moses) - The Perishing of Pharaoh and His Army

Moses is Allowed to Leave Egypt It appeared that Pharaoh would never believe in Moses's message, nor would he stop the torture of the children of Israel. Therefore, Moses prayed to his Lord thus: "Our Lord! You have indeed bestowed on Pharaoh and his chiefs splendor and wealth in the life of this world, our Lord! That they may lead men astray from Your Path. Our Lord! Destroy their wealth, and harden their hearts, so that they will not believe until they see the painful torment."
Allah said: "Verily, the invocation of you both is accepted. So you both keep to the Straight Way (i.e. keep on doing good deeds and preaching Allah's Message with patience), and follow not the path of those who know not (the truth i.e. to believe in the Oneness of Allah, and also to believe in the Reward of Allah: Paradise etc.)." Surah 10: 88-89

Musa (Moses) - The Situation after Moses is Proven Right

Pharaoh's Men Spread Rumors Pharaoh was absorbed in his new problem. A series of serious meetings began in his palace. He summoned those responsible for the army, the police and, what we call today his director of intelligence. He also summoned the ministers, princes, and priests. He called whoever had a powerful effect on the direction of events.
Pharaoh asked his director of intelligence: "What do people say?"
He said: "My men have spread among them that Moses won the contest because of a plot and that a major magician has joined with him in this plan. The plot has been disclosed, and we believe an unknown authority financed it."
Pharaoh asked his director of police: "What about the magicians' corpses?"
He said: "My men hung them in public squares and markets to terrify the people. We will spread a rumor that Pharaoh will kill whoever had anything to do with the plot."

Musa (Moses) - The Story of Moses

Description of the Pharaoh The pharaoh who ruled Egypt was a tyrant who oppressed the descendants of Jacob , known as the children of Israel (Bani Israel). He used every means to demean and disgrace them. They were kept in bondage and forced to work for him for small wages or nothing. Under this system the people obeyed and worshipped the pharaoh, and the ruling class carried out his orders, thereby authorizing his tyranny and crazy whims.
The pharaoh wanted the people to obey him only, and to believe in the gods of his invention. Perhaps, during that time, there were many classes of people who did not believe in or practice polytheism; however, they kept this to themselves and outwardly did as they were expected to do, without revolting or revealing themselves to anyone.
Thus, successive dynasties came to Egypt and assumed that they were gods or their representatives or spokesmen.

Lut (Lot) - Angels Come to Meet Lot

If home is the place of comfort and rest, then Lot found none, for he was tormented both inside and outside his home. His life was continuous torture and he suffered greatly, but he remained patient and steadfast with his people. The years rolled by, and still not one believed in him. Instead, they belittled his message and mockingly challenged him: "Bring Allah's Torment upon us if you are one of the truthful." Surah 29: 29
Overwhelmed with despair, Lot prayed to Allah to grant him victory and destroy the corrupt. Therefore, the angels left Abraham and headed for Sodom the town of Lot . They reached the walls of the town in the afternoon. The first person who caught sight of them was Lot's daughter, who was sitting beside the river, filling her jug with water. When she lifted her face and saw them, she was stunned that there could be men of such magnificent beauty on earth.

Lut (Lot) - Description of the People of Sodom

Prophet Abraham left Egypt accompanied by his nephew Lot , who then went to the city of Sodom (Sadum), which was on the western shore of the Dead Sea.
This city was filled with evil. Its residents waylaid, robbed and killed travelers. Another common evil among them was that men had sex with men instead of with women. This unnatural act later became known as sodomy (after the city of Sodom). It was practiced openly and unashamedly.

Idris (Enoch) - Birth and Teachings

Enoch was born and raised in Babylon following the teachings and religion of Prophet Adam and his son Seth. Enoch was the fifth generation of the Prophet Adam. He called the people back to his forefathers' religion, but only a few listened to him, while the majority turned away.
Prophet Enoch and his followers left Babylon for Egypt. There he carried on his mission, calling people to what is just and fair, teaching them certain prayers and instructing them to fast on certain days and to give a portion of their wealth to the poor.

Dawud (David) - Saul Plots to Kill David

Unfortunately, this only increased Saul's fear, so he plotted to kill David. Such is jealousy that not even a daughter's well-being mattered. Michal learned of her father's plan and hurried to warn her husband. David gathered some food and things, mounted his camel, and fled. He found a cave in which he remained hidden for many days.
After a time, David's brothers and some citizens joined forces with him. Saul's position became very weak, for he began to rule with a heavy hand. He ill-treated the learned, tortured the reciters of the Talmud, and terrorized his soldiers. This worsened his position, and his subjects began to turn against him. He decided to go to war against David. Hearing this news, David marched to confront Saul's army.

Dawud (David) - Daivd is Granted the Language of Animals

David recited his scripture and glorified Allah while the mountains joined him in praise and the birds rallied around him. Almighty Allah directed: Be patient (0 Muhammad) of what they say, and remember Our slave David, endued with power. Verily, he was ever oft-returning in all matters and in repentance (toward Allah.) Surah 38: 17
David's sincerity was not the only factor responsible for the birds and beasts joining with him in glorifying Allah, nor was the sweetness of his voice. It was a miracle from Allah. This was not his only miracle, for Allah also endowed him with the faculty of understanding the languages of birds and animals.

Dawud (David) - David Becomes a Prophet

David became the most famous man among the Israelites. However, he was not inveigled by this; he was not a prisoner of fame or leadership but a prisoner of Allah's love.
Therefore, after killing Goliath he went out into the desert in the company of nature, glorifying Almighty Allah and contemplating His favors.
Verily, We made the mountains to glorify Our Praises with him (David) in the Ashi (i.e. after the mid-day till sunset) and Ishraq (after the sunrise till mid-day). And (so did) the birds assembled: all with him (David) did turn (to Allah i.e. glorified His Praises). We made his kingdom strong and gave him wisdom and so und judgment in speech and decision. Surah 38: 18-20
Creatures such as the plants, birds, beasts, and even the mountains responded to his voice glorifying Allah. Allah had chosen David to be a prophet and revealed the Psalms to him. As He the Almighty said: ... and to David We gave the Psalms. Surah 17: 55
