Narrated Abu Sa`id Al−Khudri: The Prophet said, "Amongst the men of Bani Israel there was a man who had murdered ninety−nine persons. Then he set out asking (whether his repentance could be accepted or not). He came upon a monk and asked him if his repentance could be accepted. The monk replied in the negative and so the man killed him. He kept on asking till a man advised to go to such and such village. (So he left for it) but death overtook him on the way. While dying, he turned his chest towards that village (where he had hoped his repentance would be accepted), and so the angels of mercy and the angels of punishment quarrelled amongst themselves regarding him. Allah ordered the village (towards which he was going) to come closer to him, and ordered the village (whence he had come), to go far away, and then He ordered the angels to measure the distances between his body and the two villages. So he was found to be one span closer to the village (he was going to). So he was forgiven."

Abu Sa'id al−Khudri reported Allah's Messenger (may peace beupon him) as saying: There was a person before you who had killed ninety−nine persons and then made an inquiry about the learned persons of the world (who could show him the way to salvation). He was directed to a monk. He came to him and told him that he had killed ninety−nine persons and asked him whether there was any scope for his repentance to be accepted. He said: No. He killed him also and thus completed one hundred. He then asked about the learned persons of the earth and he was directed to a scholar, and he told him that he had killed one hundred persons and asked him whether there was any scope for his repentance to be accepted. He said: Yes; what stands between you and the repentance? You better go to such and such land; there are people devoted to prayer and worship and you also worship along with them and do not come to the land of yours since it was an evil land (for you). So he went away and he had hardly covered half the distance when death came to him and there was a dispute between the angels of mercy and the angels of punishment. The angels of mercy said: This man has come as a penitant and remorseful to Allah and the angels of punishment said: He has done no good at all. Then there came another angel in the form of a human being in order to decide between them. He said: You measure the land to which he has drawn near. They measured it and found him nearer to the land where he intended to go (the land of piety), and so the angels of mercy took possession of it. Qatada said that Hasan told him that it was said to them that as death approached him, he crawled upon his chest (and managed) to slip in the land of mercy.

Abu Sa'id al−Khudri reported Allah's Messenger (may peace be upon him) as saying that a man killed ninety−nine persons and then he began to make an inquiry whether there was any way left for him for repentance. He came to a monk and asked him about that, and he said: There is no chance for repentance for you. He killed the monk also and then began to make an inquiry and moved from one village to another village where there lived pious persons, and as he had covered some distance, he was overtaken by death, but he managed to crawl upon his chest(to the side nearer to the place where the pious men lived).
He died and then there was a dispute between the angels of mercy and the angels of punishment and (when it was measured) he was found to be nearer to the village where pious persons were living equal to the Space of a span and he was thus included among them.

This hadith has been narrated on the authority of Qatida with the same chain of transmitters but (with this variation of wording):" Allah commanded the earth (from where) he wanted to come out to move itself away and to the other earth (where he wanted to go) to draw nearer."
