The Prophet ﷺ said, "Whoever said "None has the right to be worshipped but Allah and has in his heart good (faith) equal to the weight of a barley grain will be taken out of Hell. And whoever said: "None has the right to be worshipped but Allah and has in his heart good (faith) equal to the weight of a wheat grain will be taken out of Hell. And whoever said, "None has the right to be worshipped but Allah and has in his heart good (faith) equal to the weight of an atom will be taken out of Hell."  

عَنِ النَّبِيِّ ﷺ قَالَ يَخْرُجُ مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَفِي قَلْبِهِ وَزْنُ شَعِيرَةٍ مِنْ خَيْرٍ وَيَخْرُجُ مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَفِي قَلْبِهِ وَزْنُ بُرَّةٍ مِنْ خَيْرٍ وَيَخْرُجُ مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَفِي قَلْبِهِ وَزْنُ ذَرَّةٍ مِنْ خَيْرٍ قَالَ أَبُو عَبْدِ اللَّهِ قَالَ أَبَانُ حَدَّثَنَا قَتَادَةُ حَدَّثَنَا أَنَسٌ عَنِ النَّبِيِّ ﷺ مِنْ إِيمَانٍ مَكَانَ مِنْ خَيْرٍ  

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.  

قَالَ رَسُولُ اللَّهِ ﷺ 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 ﷺ 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 ﷺ بِالْحَدِيثِ إِلاَّ أَنَّ شُعْبَةَ جَعَلَ مَكَانَ الذَّرَّةِ ذُرَةً قَالَ يَزِيدُ صَحَّفَ فِيهَا أَبُو بِسْطَامٍ  

“Some will exit the Fire,” Shuʿbah (another narrator) narrated it: 'Remove from the Fire whoever said La ilaha illallah and had good in his heart equal to the weight of a grain of barley. Remove from the Fire anyone who said La Ilaha illallah and had good in his heart equal to the weight of a grain of wheat. Remove from the Fire anyone who said La ilaha illallah and had good in his heart equal to the weight of a speck.” And Shubah said: “What is equal to the weight of a light piece of corn.” (Sahih) Other chains report similar narrations. (Using translation from Tirmidhī 2593)

قَالَ رَسُولُ اللهِ ﷺ أَخْرِجُوا مِنَ النَّارِ وَقَالَ حَجَّاجٌ يَقُولُ اللهُ ﷻ أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لَا إِلَهَ إِلَّا اللهُ وَمَنْ كَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ ذَرَّةً أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لَا إِلَهَ إِلَّا اللهُ مَنْ كَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ شَعِيرَةً أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لَا إِلَهَ إِلَّا اللهُ مَنْ كَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ بُرَّةً
