Musnad Ahmad 27:1870

'Abd al-Razzaq narrated to us, Ma'mar informed us, from al-Zuhri, from Salim, from Ibn 'Umar, who said: During the lifetime of the Messenger of Allah (peace and blessings of Allah be upon him), when a man saw a dream, he would narrate it to the Prophet (peace and blessings of Allah be upon him). I wished to see a dream so that I could narrate it to the Prophet (peace and blessings of Allah be upon him). I was a young, unmarried boy, and I used to sleep in the mosque during the time of the Messenger of Allah (peace and blessings of Allah be upon him). I saw in my sleep as if two angels took me and went with me to the Fire. It was built like the construction of a well, and it had two horns, and there were people in it whom I recognized. I began to say: "I seek refuge in Allah from the Fire, I seek refuge in Allah from the Fire." Then another angel met them and said to me: "You will not be afraid." I narrated it to Hafsah, and Hafsah narrated it to the Messenger of Allah (peace and blessings of Allah be upon him). He said: "What an excellent man 'Abdullah is, if only he would pray at night." Salim said: After that, 'Abdullah would not sleep at night except for a little.
