Narrated Abu Dhar (RA): Allahs Apostle ﷺ said, "While I was at Makkah the roof of my house was opened and Gabriel (علیہ السلام) descended, opened my chest, and washed it with Zam-zam water. Then he brought a golden tray full of wisdom and faith and having poured its contents into my chest, he closed it. Then he took my hand and ascended with me to the nearest heaven, when I reached the nearest heaven, Gabriel (علیہ السلام) said to the gatekeeper of the heaven, Open (the gate). The gatekeeper asked, Who is it? Gabriel (علیہ السلام) answered: Gabriel (علیہ السلام). He asked, Is there anyone with you? Gabriel (علیہ السلام) replied, Yes, Muhammad ﷺ is with me. He asked, Has he been called? Gabriel (علیہ السلام) said, Yes. So the gate was opened and we went over the nearest heaven and there we saw a man sitting with some people on his right and some on his left. When he looked towards his right, he laughed and when he looked toward his left he wept. Then he said, Welcome! O pious Prophet ﷺ and pious son. I asked Gabriel (علیہ السلام), Who is he? He replied, He is Adam and the people on his right and left are the souls of his offspring. Those on his right are the people of Paradise and those on his left are the people of Hell and when he looks towards his right he laughs and when he looks towards his left he weeps.
Then he ascended with me till he reached the second heaven and he ( Gabriel (علیہ السلام)) said to its gatekeeper, Open (the gate). The gatekeeper said to him the same as the gatekeeper of the first heaven had said and he opened the gate. Anas (RA) said: "Abu Dhar (RA) added that the Prophet ﷺ met Adam, Idris, Moses (علیہ السلام), Jesus and Abraham, he (Abu Dhar (RA)) did not mention on which heaven they were but he mentioned that he (the Prophet) met Adarn on the nearest heaven and Abraham on the sixth heaven. Anas (RA) said, "When Gabriel (علیہ السلام) along with the Prophet ﷺ passed by Idris, the latter said, Welcome! O pious Prophet ﷺ and pious brother. The Prophet ﷺ asked, Who is he? Gabriel (علیہ السلام) replied, He is Idris." The Prophet ﷺ added, "I passed by Moses (علیہ السلام) and he said, Welcome! O pious Prophet ﷺ and pious brother. I asked Gabriel (علیہ السلام), Who is he? Gabriel (علیہ السلام) replied, He is Moses (علیہ السلام). Then I passed by Jesus and he said, Welcome! O pious brother and pious Prophet. I asked, Who is he? Gabriel (علیہ السلام) replied, He is Jesus.
Then I passed by Abraham and he said, Welcome! O pious Prophet ﷺ and pious son. I asked Gabriel (علیہ السلام), Who is he? Gabriel (علیہ السلام) replied, He is Abraham. The Prophet ﷺ added, Then Gabriel (علیہ السلام) ascended with me to a place where I heard the creaking of the pens." Ibn Hazm and Anas bin Malik (RA) said: The Prophet ﷺ said, "Then Allah enjoined fifty prayers on my followers when I returned with this order of Allah; I passed by Moses (علیہ السلام) who asked me, What has Allah enjoined on your followers? I replied, He has enjoined fifty prayers on them. Moses (علیہ السلام) said, Go back to your Lord (and appeal for reduction) for your followers will not be able to bear it. (So I went back to Allah and requested for reduction) and He reduced it to half. When I passed by Moses (علیہ السلام) again and informed him about it, he said, Go back to your Lord as your followers will not be able to bear it. So I returned to Allah and requested for further reduction and half of it was reduced. I again passed by Moses (علیہ السلام) and he said to me: Return to your Lord, for your followers will not be able to bear it. So I returned to Allah and He said, These are five prayers and they are all (equal to) fifty (in reward) for My Word does not change. I returned to Moses (علیہ السلام) and he told me to go back once again. I replied, Now I feel shy of asking my Lord again. Then Gabriel (علیہ السلام) took me till we reached Sidrat-il-Muntaha (Lote tree of; the utmost boundry) which was shrouded in colors, indescribable. Then I was admitted into Paradise where I found small (tents or) walls (made) of pearls and its earth was of musk.
