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  

“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.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ قَالَ هِشَامٌ يَخْرُجُ مِنَ النَّارِ وَقَالَ شُعْبَةُ أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَكَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ شَعِيرَةً أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَكَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ بُرَّةً أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَكَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ ذَرَّةً وَقَالَ شُعْبَةُ مَا يَزِنُ ذُرَةً مُخَفَّفَةً وَفِي الْبَابِ عَنْ جَابِرٍ وَعِمْرَانَ بْنِ حُصَيْنٍ

(Using translation from Tirmidhī 2593)   

قَالَ رَسُولُ اللهِ ﷺ أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لَا إِلَهَ إِلَّا اللهُ مَنْ كَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُشَعِيرَةً أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لَا إِلَهَ إِلَّا اللهُ مَنْ 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 بُرَّةً  

"يَخْرُجُ مِنْ النَّارِ مَنْ قَالَ: لَا إِله إِلَّا اللَّه، وكَانَ فِى قَلبه مِنَ الْخَيْرِ مَا يَزِنُ شَعِيرَةً، ثُمَّ يَخْرُجُ مِنْ النَّارِ مَنْ قَالَ: لَا إِلَهَ إِلَّا اللَّه، وَكَانَ فِى قَلبِهِ مِنَ الْخَيْرِ مَا يَزِنُ بُرَّةً، ثُمَّ يَخْرُجُ مِنَ النَّارِ مَنْ قَالَ: لَا إِلهَ إِلَّا اللَّه، وَكَانَ فِى قَلبِهِ مِنَ الْخَيْرِ مَا يَزِنُ ذَرَّةً".
