باب أَدْنَى أَهْلِ الْجَنَّةِ مَنْزِلَةً فِيهَا ‏‏
Sahih Muslim 193 d

Anas b. Malik reported:

Verily the Apostle (ﷺ) said: He who professed: There is no god but Allah, would be brought out of the Fire even though he has in his heart virtue equal to the weight of a barley grain. Then he who professed: There is no god but Allah, would come out of the Fire, even though he has in his heart virtue equal to the weight of a wheat grain. He would then bring out from the Fire he who professed: There is no god but Allah, even though he has in his heart virtue equal to the weight of an atom. Ibn Minhal has made an addition (of these words) in his narration: Yazid said: I met Shu'ba and narrated to him this hadith. Shu'ba said: Qatada transmitted to us this hadith from Anas b. Malik who heard it from the Messenger of Allah (ﷺ) with this alteration that he substituted the word Zurra (grain) in place of Zarra (atom). Yazid said: Abu Bistam has made a change in it.
وَحَدَّثَنَا مُحَمَّدُ بْنُ مِنْهَالٍ الضَّرِيرُ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا سَعِيدُ بْنُ أَبِي عَرُوبَةَ، وَهِشَامٌ، صَاحِبُ الدَّسْتَوَائِيِّ عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ح وَحَدَّثَنِي أَبُو غَسَّانَ الْمِسْمَعِيُّ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، قَالاَ حَدَّثَنَا مُعَاذٌ، - وَهُوَ ابْنُ هِشَامٍ - قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏ "‏ يَخْرُجُ مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَكَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ شَعِيرَةً ثُمَّ يَخْرُجُ مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَكَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ بُرَّةً ثُمَّ يَخْرُجُ مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَكَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ ذَرَّةً ‏"‏ ‏.‏ زَادَ ابْنُ مِنْهَالٍ فِي رِوَايَتِهِ قَالَ يَزِيدُ فَلَقِيتُ شُعْبَةَ فَحَدَّثْتُهُ بِالْحَدِيثِ فَقَالَ شُعْبَةُ حَدَّثَنَا بِهِ قَتَادَةُ عَنْ أَنَسِ بْنِ مَالِكٍ عَنِ النَّبِيِّ صلى الله عليه وسلم بِالْحَدِيثِ ‏.‏ إِلاَّ أَنَّ شُعْبَةَ جَعَلَ مَكَانَ الذَّرَّةِ ذُرَةً قَالَ يَزِيدُ صَحَّفَ فِيهَا أَبُو بِسْطَامٍ ‏.‏
