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
Tirmidhi and Ibn Majah transmitted it.
