Narrated Anas (ra):Abu Dhar (ra) used to say that Allah's Messenger (ﷺ) said, "While I was at Makkah, the roof of my house was opened and Jibril descended, opened my chest, and washed it with Zamzam 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 heaven. When Jibril reached the nearest heaven, he said to the gatekeeper of the heaven, 'Open (the gate).' The gatekeeper asked, 'who is it?' Jibril answered, 'Jibril'. He asked, 'Is there anyone with you?' Jibril replied, 'Muhammad (ﷺ) is with me.' He asked, 'Has he been called?', Jibril said, 'Yes'. So, the gate was opened and we went over the nearest heaven, and there we saw a man sitting with Aswida (a large number of people) on his right and Aswida on his left. When he looked towards his right, he laughed and when he looked towards his left he wept. He said (to me), 'Welcome, O pious Prophet and pious son'. I said, 'Who is this man O Jibril?' Jibril replied, 'He is Adam, and the people on his right and left are the souls of his offspring. Those on the right are the people of Paradise, and those on the left are the people of the (Hell) Fire. So, when he looks to the right, he laughs, and when he looks to the left he weeps.' Then Jibril ascended with me till he reached the second heaven and said to the 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 added: Abu Dhar mentioned that the Prophet (ﷺ) met Idris, Musa (Moses), 'Isa (Jesus) and Ibrahim (Abraham) over the heavens, but he did not specify their places (i.e., on which heavens each of them was), but he mentioned that he (the Prophet (ﷺ)) had met Adam on the nearest heaven, and Ibrahim on the sixth. Anas said, "When Jibril and the Prophet (ﷺ) passed by Idris, the latter said, 'Welcome, O pious Prophet and pious brother!' the Prophet (ﷺ) asked, 'Who is he?' Jibril said, 'He is Idris.' " The Prophet (ﷺ) added, "Then I passed by Musa who said, 'Welcome, O pious Prophet and pious brother!' I said, 'Who is he?' Jibril said, 'He is Musa.' Then I passed by 'Isa who said, 'Welcome, O pious Prophet and pious brother!' I said, 'Who is he?' He replied, 'He is 'Isa.' Then I passed by the Prophet (ﷺ) Ibrahim who said, 'Welcome, O pious Prophet and pious son!' I said, 'Who is he?' Jibril replied, 'He is Ibrahim'." Narrated Ibn 'Abbas and Abu Haiyya Al-Ansari: The Prophet (ﷺ) said, "Then Jibril ascended with me to a place where I heard the creaking of pens." Ibn Hazm and Anas bin Malik state that the Prophet (ﷺ) said, "Allah enjoined fifty Salat (prayers) on me. When I returned with this order of Allah, I passed by Musa who asked me, 'What has Allah enjoined on your followers?' I replied, 'He has enjoined fifty Salat (prayers) on them.' On that Musa said to me, 'Go back to your Lord (and appeal for reduction), for your followers will not be able to bear it.' So, I returned to my Lord and asked for some reduction, and He reduced it to half. When I passed by Musa again and informed him about it, he once more said to me, 'Go back to your Lord, for your followers will not be able to bear it.' So, I returned to my Lord similarly as before, and half of it was reduced. I again passed by Musa and he said to me, 'Go back to your Lord, for your followers will not be able to bear it.' I again returned to my Lord and He said, 'These are five (Salat-prayers) and they are all (equal to) fifty (in reward), for My Word does not change.' I returned to Musa, he again told me to return to my Lord (for further reduction) but I said to him 'I feel shy of asking my Lord now.' Then Jibril took me till we reached Sidrat-ul-Muntaha (i.e., lote tree of utmost boundary) which was shrouded in colors indescribable. Then I was admitted into Paradise where I found small tents (made) of pearls and its earth was musk (a kind of perfume)
