Sahih Muslim 162a

Shayban ibn Farrukh narrated to us: Hammad ibn Salama narrated to us; Thabit al-Bunani narrated to us, from Anas ibn Malik, that the Messenger of Allah (peace and blessings be upon him) said: I was brought al-Buraq, a tall white mount, larger than a donkey and smaller than a mule, whose hoof would reach as far as its gaze could see. I rode it until I came to Bayt al-Maqdis, where I tethered it to the ring used by the prophets. Then I entered the mosque and prayed two rak'as. When I came out, Gabriel, peace be upon him, brought me a vessel of wine and a vessel of milk. I chose the milk, and Gabriel said: You chose the natural way. Then he ascended with us to heaven and asked for the gate to be opened. He was asked: Who are you? He said: Gabriel. They asked: Who is with you? He said: Muhammad. They asked: Has he been sent for? He said: Yes. The gate was opened, and there was Adam. He welcomed me and prayed for good for me. Then he ascended with us to the second heaven and Gabriel asked for the gate to be opened. He was asked: Who are you? He said: Gabriel. They asked: Who is with you? He said: Muhammad. They asked: Has he been sent for? He said: Yes. The gate was opened, and there were my maternal cousins, Jesus son of Mary and John son of Zechariah, peace be upon them. They welcomed me and prayed for good for me. Then he ascended with me to the third heaven and Gabriel asked for the gate to be opened. He was asked: Who are you? He said: Gabriel. They asked: Who is with you? He said: Muhammad, peace and blessings be upon him. They asked: Has he been sent for? He said: Yes. The gate was opened, and there was Joseph, peace be upon him, who had been given half of all beauty. He welcomed me and prayed for good for me. Then he ascended with us to the fourth heaven. Gabriel, peace be upon him, asked for the gate to be opened. They asked: Who is this? He said: Gabriel. They asked: Who is with you? He said: Muhammad. They asked: Has he been sent for? He said: Yes. The gate was opened, and there was Idris. He welcomed me and prayed for good for me. Allah, Mighty and Majestic, said: We raised him to a high station. Then he ascended with us to the fifth heaven, where Gabriel asked for the gate to be opened. They asked: Who is this? He said: Gabriel. They asked: Who is with you? He said: Muhammad. They asked: Has he been sent for? He said: Yes. The gate was opened, and there was Aaron, peace be upon him. He welcomed me and prayed for good for me. Then he ascended with us to the sixth heaven. Gabriel, peace be upon him, asked for the gate to be opened. They asked: Who is this? He said: Gabriel. They asked: Who is with you? He said: Muhammad. They asked: Has he been sent for? He said: Yes. The gate was opened, and there was Moses, peace be upon him. He welcomed me and prayed for good for me. Then he ascended with us to the seventh heaven. Gabriel asked for the gate to be opened. They asked: Who is this? He said: Gabriel. They asked: Who is with you? He said: Muhammad, peace and blessings be upon him. They asked: Has he been sent for? He said: Yes. The gate was opened, and there was Abraham, peace be upon him, leaning against the Frequented House. Every day seventy thousand angels enter it and never return to it again. Then he took me to the Lote Tree of the Utmost Boundary. Its leaves were like the ears of elephants, and its fruits like large earthen jars. When it was enveloped by what Allah commanded, it changed in such a way that no creature of Allah could describe its beauty. Allah then revealed to me what He revealed and prescribed for me fifty prayers each day and night. I descended to Moses, peace be upon him, and he asked: What has your Lord prescribed for your community? I said: Fifty prayers. He said: Return to your Lord and ask Him to lighten the burden, for your community cannot bear that. I have tested the Children of Israel and know them well. I returned to my Lord and said: My Lord, lighten the burden for my community. He reduced five for me. I returned to Moses and said: He reduced five for me. He said: Your community cannot bear that; return to your Lord and ask Him to lighten it. I kept going back and forth between my Lord, Blessed and Exalted, and Moses, peace be upon him, until He said: Muhammad, they are five prayers each day and night. Each prayer counts as ten, making fifty. Whoever intends a good deed but does not do it will have one good deed recorded; if he does it, ten will be recorded. Whoever intends an evil deed but does not do it will have nothing recorded; if he does it, one evil deed will be recorded. I descended until I reached Moses, peace be upon him, and told him. He said: Return to your Lord and ask Him to lighten it. The Messenger of Allah (peace and blessings be upon him) said: I replied, I have returned to my Lord so many times that I feel ashamed before Him.
