Book Number: 031 / Hadith Number: 6090
Umm Mubashshir reported that she heard Allah's Apostle (may peace be upon him) as saying in presence of Hafsa: God willing, the people of the Tree would never enter the fire of Hell one amongst those who owed allegiance under that. She said: Allah's Messenger, why not? He scolded her. Hafsa said: And there is none amongst you but shall have to pass over that (narrow Bridge). Thereupon Allah's Apostle (may peace be upon him) said: Allah, the Exalted and Glorious, has said: We would rescue those persons who are God-conscious and we would leave the tyrants to their fate there (xix. 72).
