Here are some Incidents from the life of Prophet Muhammad

From his childhood he was called truthful and trustworthy. When he wanted to deliver the message of Allah, he asked all the people of Mecca to a hill. He stood on the top of the hill and said that if I tell you that the enemy has assembled an army to conquer Mecca, on the other side of the hill, would you believe it? All the people who had gathered said with one voice that they shall believe it. Then he delivered the message that there is only one God. But the pagans refused to believe it at that time.
The pagans of Mecca had tried all the atrocities and cruelties on the Prophet and the believers, but failed to dissuade from Islam. So they called on the Prophet as a delegation and offered thar they can make him their king, give him all the wealth that he wants and also give him the most beautiful lady in his wedlock, but he should not propagate Islam. The Prophet replied:

"If you put sun on my one hand and moon on the other hand, to give up Islam I will not, until Allah fulfills it for me or destroys me in the process."

Once his companion Hazrat Umer visited his house and burst into crying. In reply to Prophet's inquiry that what made him cry? Hazrat Umer said that the infidel emperors of Rome and Persia have all the luxuries of the world but the household of our ruler, the Prophet, consists only of one rough bedstead, an old leather water container and some barley. The Prophet replied that it is not better that we shall have all those luxuries in the eternal life i.e. life after death.

One day he was alone and sleeping under a tree when a pagan pointed his sword to the Prophet's chest and asked as to who would save him? The Prophet undisturbed replied that Allah shall save him. The pagan got so scared, dropped his sword and embraced Islam.

An old woman used to throw rubbish on the Prophet when he used to pass by her street. One day the Prophet did not find her and enquired about her. He was told that she was sick. He went to visit her and prayed for her health. She wept and embraced Islam.

Once a daughter of an influential chieftain was awarded punishment for stealing. A number of people interceded on her behalf and requested for pardon. The Prophet got very angry and said that double standard of justice where ordinary people are punished whereas the rich are dealt otherwise, has caused the ruination of many nations.

The Prophet never ever refused anything to the needy. If he did not have it, he borrowed it. On his death his arms were mortged with a Jew, because he had borrowed money for a needy person. Many a times it happened that there was very little to eat in the house of the Prophet and a needy person asked for something to eat. The prophet gave the food to him and he himself remained hungry.

Once he put on a new dress. Someone asked for the dress and he gave it to him and he himself put on an old one. Once a person from a different tribe asked for his whole flock of goats which was of considerable numbers. He gave it to him!
Once he visited a garden and found a camel crying with hunger. He admonished the owners that are you not afraid of God in respect of this animal?
