Musnad Ahmad

Narrated to us Yunus ibn Muhammad, narrated to us Shayban, from Qatadah, who said: Anas ibn Malik narrated to us that Malik ibn Sa'sa'ah narrated to them, that the Prophet of Allah, peace and blessings be upon him, said: "While I was at the Ka'bah, between sleep and wakefulness," and he mentioned the hadith, he said: "Then we ascended to the seventh heaven, and Jibril, peace be upon him, sought permission to enter. It was said: Who is this? It was said: Jibril. It was said: And who is with you? It was said: Muhammad. It was said: Has he been sent for? He said: Yes. So it was opened for him, and they said: Welcome to him, and what a good arrival he has come. So we came upon Ibrahim, peace be upon him. I said: Who is this? Jibril said: This is your father Ibrahim. So I greeted him, and he said: Welcome, O righteous son and righteous prophet. Then the Lote Tree of the Utmost Boundary was raised for me, and its leaves were like the ears of elephants, and its fruits like the jars of Hajar, and there were four rivers coming out from its root: two visible rivers and two hidden rivers. I said: What are these, O Jibril? He said: As for the two visible rivers, they are the Nile and the Euphrates, and as for the two hidden rivers, they are two rivers in Paradise. He said: Then two vessels were brought to me, one of them containing wine and the other milk. He said: I took the milk, so Jibril said: You have chosen the natural disposition."
