حَدَّثَنَا سَلَمَةُ بْنُ شَبِيبٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " يُخْرَجُ مِنَ النَّارِ مَنْ كَانَ فِي قَلْبِهِ مِثْقَالُ ذَرَّةٍ مِنَ الإِيمَانِ " . قَالَ أَبُو سَعِيدٍ فَمَنْ شَكَّ فَلْيَقْرَأْ: (إِنَّ اللَّهَ لاَ يَظْلِمُ مِثْقَالَ ذَرَّةٍ ) . قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .

Abu Sa‘id al-Khudri reported that the Prophet said: ‘Whoever has an atom’s weight of faith in his heart will be brought out of the Fire.’ Abu Sa‘id said: ‘If anyone has doubts, let him recite: “Indeed, Allah does not wrong anyone by even an atom’s weight.”’ Abu ‘Isa said: ‘This hadith is hasan sahih.’
Notes and open questions — unreviewed
The hadith says the person will be brought out of the Fire; Abu Sa‘id then cites the verse as a response to doubt.
