Sayyiduna Samurah bin Jundub (may Allah be pleased with him) narrates: When the Messenger of Allah (peace and blessings be upon him) began the morning, he would say: "Has any of you seen a dream?" Then he (peace and blessings be upon him) would interpret it, until one day he (peace and blessings be upon him) began the morning and said: "Has any of you seen a dream?" The people remained silent, so he (peace and blessings be upon him) said: "But I saw in a dream: two men came to me, and they both said to me: 'Go on.' So I passed with them by a man who had a rock in his hand. He was striking a man's head with it and scattering his brain, then the rock would return to his hand and his head would become as it was before - he said - so I said: 'What is this?' They both said: 'Go on.' So I passed with them by a man who had an iron hook in his hand, with which he was tearing a man's jaw, until when he reached its farthest end he would start on the other jaw, and this first jaw would become as it was before. I said: 'What is this?' They both said to me: 'Go on.' So I passed with them by a man who was in a river of blood, and (the blood) had reached his mouth, and on the bank of the river was a man kindling a fire in which there were stones. Whenever he (the man in the river of blood) wanted to come out, he would take a stone from it and throw it into his mouth, and he would go back. I said: 'What is this?' They both said to me: 'Go on.' So I passed with them by a house whose lower part was narrower than its upper part. In it were some people who were naked, and a fire would be kindled beneath them. Whenever the fire was kindled they would cry out, and when it was extinguished they would become quiet. I said: 'What is this?' They both said to me: 'Go on.' So I passed with them by a tree beneath which a man was kindling a fire and tending it; whenever it scattered he would gather it again. I said: 'What is this?' They both said to me: 'Go on.' Until they both brought me to the middle of the tree, and there were beautiful dwellings. I said: 'What is this?' They both said to me: 'Go on.' So they both took me to the upper part of the tree, and there were dwellings even better than those, and there were three upper chambers. I said: 'What is this?' They both said: 'Wait a moment. (Now listen:) The man who had a rock in his hand and was striking the other man's head with it, they are those who sleep (heedlessly) through the prayer - and Ibn Abbas (may Allah be pleased with them both) said: This is the one who was given knowledge, and he used to be awakened for it - and the man whom you saw with a hook in his hand with which he was tearing a man's jaw, they are those who spread tales (slander). And the man whom you saw in the river of blood, they are the consumers of usury (riba). And the (house) which you saw whose lower part was narrower than its upper part, with naked people in it, they are the adulterers of this Ummah, and they will remain like that until the Day of Resurrection. And the man whom you saw beneath the tree kindling the fire and tending it, that is Malik, the keeper of the Fire. And the dwellings which you saw in the middle of the tree are the dwellings of the believers in general, and these (upper ones) are the dwellings of the prophets, the truthful (siddiqin) and the martyrs, and this upper chamber is for you. And I am Jibril, and this is Mika'il.'"
