Book Number: 004 / Hadith Number: 1737
Narated By Umm Salamah, Ummul Mu'minin : She heard the Apostle of Allah (pbuh) say: If anyone puts on ihram for hajj or umrah from the Aqsa mosque to the sacred mosque, his former and latter sins will be forgiven, or he will be guaranteed Paradise. The narrator Abdullah doubted which of these words he said.
