after that momentous day in the month of ramadan, revelation came again and again to the prophet (pbuh). he understood now what he had to do and prepared himself for what was to come. only a strong and brave man, helped by allah, can be a true prophet because people often refuse to listen to allah's message. khadijah was the first to believe the prophet (pbuh) and accept as true what he brought from allah. through her, allah made things easier for the prophet (pbuh). khadijah strengthened him, helped him spread his message, and stood up to the people who were against him.
then revelation ceased for a time. the prophet (pbuh) was upset and unhappy, thinking that allah had left him, or that he might have angered allah in some way so that allah no longer thought him worthy of his message. however, the archangel gabriel came back to him and brought this surah, or chapter, of the koran:
in the name of allah, the beneficent, the merciful
"by the morning hours,and by the night when it is stillest, thy lord hath neither forsaken thee nor doth he hate thee, and verily the last will be better for thee than the first. and verily thy lord will give unto thee so that thou wilt be content. did he not find thee an orphan and protect thee? did he not find thee wandering and guide thee? did he not find thee destitute and enrich thee? therefore the orphan oppress not, therefore the beggar drive not away, and as for thy lord's blessing, declare it". (koran: xciii.1-11)

the prophet (pbuh) began to speak secretly of allah's message to those who were close to him and whom he could trust. at that time mecca was going through hard times. there was very little food to be had. abu talib, the prophet's uncle, who had taken care of him after his grandfather's death, was finding it very difficult to feed his large family.

the prophet (pbuh) said that he and another uncle, al-'abbas, who was a rich man,

would each bring up one of abu talib's children in order to help him. the prophet (pbuh) took 'ali and his uncle took ja'far.
one day, when the prophet (pbuh) was outside the city, the archangel gabriel appeared to him. the archangel kicked the side of a hill and a spring of water began to flow out. he then began to wash himself in the running water to show the prophet (pbuh) the ritual ablution to be made before prayer. then the archangel showed him all the positions of muslim prayer-the various movements and things to be said with each movement. the prophet (pbuh) returned home and taught all these things first to khadijah and then to his followers. since then muslims have continued to purify themselves before prayer by performing the ritual ablution and have followed the same movements and prayers first performed by the prophet (pbuh). to begin with, though, only the prophet (pbuh) and his wife knew of these things. then one day 'ali entered the room and found the prophet (pbuh) and khadijah praying.

he was puzzled and asked what they were doing. the prophet (pbuh) explained to him that they were praising allah and giving thanks to him. that night 'ali stayed up thinking about all that the prophet (pbuh) had said; he had great admiration and respect for his cousin. finally he came to a decision and the next day he went to the prophet (pbuh) and told him that he wanted to follow him. thus khadijah was the first woman to embrace islam, the teachings which the prophet (pbuh) brought from allah, and 'ali was the first young man. shortly after they were joined by zayd ibn harithah, a slave, freed and adopted by the prophet (pbuh).
the prophet (pbuh) began to leave mecca with ali in order to pray. one day abu talib happened to pass by and when he saw them he stopped and asked them what they were doing. the prophet (pbuh) told him that they were praying and following the same religion as abraham. he explained that, like abraham, he had been ordered to guide the people to allah's truth. abu talib looked at his son,

'ali, and said: 'muhammad (pbuh) would never make you do anything that was wrong. go with him.
but i cannot leave the religion i now follow and which was followed by my father.' then he turned to the prophet (pbuh), saying, 'even so, i promise you, muhammad (pbuh), that no one will hurt you as long as i am alive.' and with that abu talib went on his way. at about this time the news of muhammad (pbuh) being the prophet reached an honest, wise, and respected merchant of mecca called abu bakr. he knew muhammad (pbuh) well and believed he could never lie, so he went to find out for himself if the story were true. the prophet (pbuh) told him that he had indeed been sent by allah to teach everyone to worship the one true allah. on hearing this from the prophet's own lips abu bakr knew it to be the truth and became a believer instantly. later the prophet (pbuh) was reported to have said that everyone he ever invited to accept islam showed signs of disbelief and doubt, except abu bakr; when he was told of it he did not hold back or hesitate.

because of his wisdom, honesty, and kindness people had always turned to abu bakr for advice. he was, therefore, a man of some influence and through him many people came to islam. among these was sa'd ibn abi waqqas as, the uncle of aminah, the prophet's mother. the night before abu bakr came to visit him and tell him about islam, sa'd ibn abi waqqas dreamt that he was walking in darkness. as he walked he saw the moon and when he looked at it he saw 'ali, abu bakr, and zayd, the prophet's freed slave, beckoning to him to come and join them. when abu bakr told him about the prophet's religion, he understood the meaning of his dream and went at once to the prophet (pbuh) and declared himself a muslim. he understood that to be a muslim means to submit oneself to allah's will and to serve only him. another person brought to islam by abu bakr was bilal. one night abu bakr went to the house of umayyah ibn khalaf, one of the most important men of quraysh. umayyah was out and abu bakr found only umayyah's slave, bilal, at home. abu bakr talked to the slave about islam and before he left, bilal, too, had become a muslim. the number of people following the prophet (pbuh) began to grow. sometimes they would all go out of the city to the mountains around mecca to hear him recite the koran and to be taught by him. this was all done very secretly and only a very few people knew about islam in those early days.
