I was a young unmarried man during the lifetime of the Prophet. I used to sleep in the mosque. Anyone who had a dream, would narrate it to the Prophet. I said, "O Allah! If there is any good for me with You, then show me a dream so that Allah's Messenger (ﷺ) may interpret it for me." So I slept and saw (in a dream) two angels came to me and took me along with them, and they met another angel who said to me, "Don't be afraid, you are a good man." They took me towards the Fire, and behold, it was built inside like a well, and therein I saw people some of whom I recognized, and then the angels took me to the right side. In the morning, I mentioned that dream to Hafsa. Hafsa told me that she had mentioned it to the Prophet (ﷺ) and he said, "`Abdullah is a righteous man if he only prays more at night." (Az-Zuhri said, "After that, `Abdullah used to pray more at night.")

← Previous Hadith Men from the companions of Allah's Messenger (ﷺ) used to see dreams during the lifetime of Allah's Messenger (ﷺ) and they used to narrate those dreams to Allah's Messenger (ﷺ). Allah's Messenger (ﷺ) would interpret them as Allah wished. I was a young man and used to stay in the mosque before my wedlock. I said to myself, "If there were any good in myself, I too would see what these people see." So when I went to bed one night, I said, "O Allah! If you see any good in me, show me a good dream." So while I was in that state, there came to me (in a dream) two angels. In the hand of each of them, there was a mace of iron, and both of them were taking me to Hell, and I was between them, invoking Allah, "O Allah! I seek refuge with You from Hell." Then I saw myself being confronted by another angel holding a mace of iron in his hand. He said to me, "Do not be afraid, you will be an excellent man if you only pray more often." So they took me till they stopped me at the edge of Hell, and behold, it was built inside like a well and it had side posts like those of a well, and beside each post there was an angel carrying an iron mace. I saw therein many people hanging upside down with iron chains, and I recognized therein some men from the Quraish. Then (the angels) took me to the right side. I narrated this dream to (my sister) Hafsa and she told it to Allah's Messenger (ﷺ). Allah's Messenger (ﷺ) said, "No doubt, `Abdullah is a good man." (Nafi` said, "Since then `Abdullah bin `Umar used to pray much.)

They asked. What have you interpreted (about the dream)? O Allah's Messenger (ﷺ)?" The Prophet (ﷺ) said. "(It is Religious) knowledge."
