Sunan Ibn Majah 4070

It was narrated from Safwan bin ‘Assal that the Messenger of Allah (ﷺ) said:“Towards the west (i.e., the place of the setting of the sun) there is an open door, seventy years wide. That door will remain open for repentance until the sun rises from this direction. When it rises from this direction, faith will not benefit any soul that did not believe before or earn anything good through its faith.”
