Ibn Shihab told on the authority of Anas that Abu Dharr used to tell that God's messenger said, "The roof of my house was cleft when I was in Mecca and Gabriel descended and opened my breast, after which he washed it with Zamzam water. He then brought a gold dish full of wisdom and faith, and after emptying it into my breast he closed it up. Then taking me by the hand he ascended with me to heaven, and when I came to the lowest heaven Gabriel said to the guardian of heaven, `Open.' He asked who was there, and when he replied that it was Gabriel, he asked whether anyone was with him. When he replied that he had Muhammad with him he was asked whether he had been sent for and replied that he had. When the gate was opened, we went up into the lowest heaven and I saw a man sitting with people on his right and people on his left. When he looked to his right he laughed, and when he looked to his left he wept. He said, `Welcome to the good prophet and the good son.' I asked Gabriel who this was and he replied, `This is Adam, and these people on his right and his left are the souls of his descendants. Those of them on his right are the inhabitants of paradise and those on his left are the inhabitants of hell, so when he looks to his right he laughs and when he looks to his left he weeps.' He then took me up to the second heaven and said to its guardian, `Open,' and its guardian said to him the same as the first one had said." Anas said he mentioned that he had found in the heavens Adam, Idris, Moses, Jesus and Abraham, hut did not specify the nature of their abodes, except th a t he mentioned he had found Adam in the lowest heaven and Abraham in the sixth. Ibn Shihab said he was told by Ibn Hazm that Ibn `Abbas and Abu Habba al-Ansar! used to say that the Prophet said, "I was then taken up till I mounted a height in which I heard the scraping of the pens." Ibn Hazm and Anas told that the Prophet said, ``God then made fifty prayers obligatory for my people and I returned with that. When I passed Moses, he asked what God had made it obligatory for me to impose on my people, and when I told him He had made fifty I prayers obligatory he said, `Go back to your Lord, for your people are | not capable.' So, he sent me back and half of them were remitted, and i! when I returned to Moses and told him that half of them had been i remitted, he said, `Go back to your Lord, for your people are not capable.' I went back and repeated what I had said, and half of them were remitted. I then returned to him and he said, `Go back to your Lord, for your I people are not capable of that.' I went back to Him and He said, `They are five and at the same time fifty. What has been said is not changed with Me.' I then returned to Moses, and when he told me to go back to my Lord I replied, `I am ashamed to face my Lord.' He then travelled; with me till he brought me to the lote-tree of the boundary covered with colours, what they were I do not know. I was then brought into paradise and saw in it domes of pearls, and its soil was musk." (Bukhari and Muslim.)
