Safwan b. ‘Assal reported God’s messenger as saying, “God most high has placed in the west for repentance a gate with a breadth of seventy years’ journey, and it will not be locked as long the sun does not rise in its direction. That agrees with God’s words, ‘On the day that certain of the signs of your Lord come, a soul which has not believed before will not be benefited by believing in them ’.”*
*Qur’an, vi, 158
Abu Sa'id reported God’s messenger as saying that the devil said, “By Thy might, my Lord, I shall continue to lead Thy servants astray as long as their spirits are in their bodies” The Lord who is great and glorious replied, “By my might, glory and exalted station, I shall con tinue to pardon them as long as they ask my forgiveness.”
Mu'awiya reported God’s messenger as saying, "Emigration will not come to an end* till repentance comes to an end and repentance will not come to an end till the sun rises in-the place where it sets.”
*This probably means that people will continue to leave districts in which it is difficult for them to observe their religion.
Ibn ‘Umar reported God’s messenger as saying, “God accepts a servant’s repentance till he gives up his spirit in death.”*
*The Arabic is ma lam yugharghir, which might, be translated literally "as long as he has not died with the death rattle in his throat."
