باب مِنْ فَضَائِلِ أَصْحَابِ الشَّجَرَةِ أَهْلِ بَيْعَةِ الرِّضْوَانِ رضى الله عنهم ‏‏
Sahih Muslim 2496

Umm Mubashshir reported that she heard Allah's Apostle (ﷺ) 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 (ﷺ) 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).
حَدَّثَنِي هَارُونُ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا حَجَّاجُ بْنُ مُحَمَّدٍ، قَالَ قَالَ ابْنُ جُرَيْجٍ أَخْبَرَنِي أَبُو الزُّبَيْرِ، أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ أَخْبَرَتْنِي أُمُّ مُبَشِّرٍ، أَنَّهَا سَمِعَتِ النَّبِيَّ صلى الله عليه وسلم يَقُولُ عِنْدَ حَفْصَةَ ‏"‏ لاَ يَدْخُلُ النَّارَ إِنْ شَاءَ اللَّهُ مِنْ أَصْحَابِ الشَّجَرَةِ أَحَدٌ ‏.‏ الَّذِينَ بَايَعُوا تَحْتَهَا ‏"‏ ‏.‏ قَالَتْ بَلَى يَا رَسُولَ اللَّهِ ‏.‏ فَانْتَهَرَهَا فَقَالَتْ حَفْصَةُ ‏{‏ وَإِنْ مِنْكُمْ إِلاَّ وَارِدُهَا‏}‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ قَدْ قَالَ اللَّهُ عَزَّ وَجَلَّ ‏{‏ ثُمَّ نُنَجِّي الَّذِينَ اتَّقَوْا وَنَذَرُ الظَّالِمِينَ فِيهَا جِثِيًّا‏}
