إِنَّ اللَّهَ لاَ يَظْلِمُ مِثْقَالَ ذَرَّةٍ وَإِنْ تَكُ حَسَنَةً يُضَاعِفْهَا وَيُؤْتِ مِنْ لَدُنْهُ أَجْرًا عَظِيمًا

‘Surely, Allah wrongs not even of the weight of an atom, but is there is any good, He doubles it, and gives from Him a great reward’.” — Qur’an 4: 40

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏

إِذَا خَلَّصَ اللَّهُ الْمُؤْمِنِينَ مِنَ النَّارِ وَأَمِنُوا

فَمَا مُجَادَلَةُ أَحَدِكُمْ لِصَاحِبِهِ فِي الْحَقِّ يَكُونُ لَهُ فِي الدُّنْيَا أَشَدَّ مُجَادَلَةً مِنَ الْمُؤْمِنِينَ لِرَبِّهِمْ فِي إِخْوَانِهِمُ الَّذِينَ أُدْخِلُوا النَّارَ

قَالَ يَقُولُونَ رَبَّنَا إِخْوَانُنَا كَانُوا يُصَلُّونَ مَعَنَا وَيَصُومُونَ مَعَنَا وَيَحُجُّونَ مَعَنَا فَأَدْخَلْتَهُمُ النَّارَ

فَيَقُولُ اذْهَبُوا فَأَخْرِجُوا مَنْ عَرَفْتُمْ مِنْهُمْ

فَيَأْتُونَهُمْ فَيَعْرِفُونَهُمْ بِصُوَرِهِمْ لاَ تَأْكُلُ النَّارُ صُوَرَهُمْ فَمِنْهُمْ مَنْ أَخَذَتْهُ النَّارُ إِلَى أَنْصَافِ سَاقَيْهِ وَمِنْهُمْ مَنْ أَخَذَتْهُ إِلَى كَعْبَيْهِ

فَيُخْرِجُونَهُمْ فَيَقُولُونَ رَبَّنَا أَخْرَجْنَا مَنْ قَدْ أَمَرْتَنَا

ثُمَّ يَقُولُ أَخْرِجُوا مَنْ كَانَ فِي قَلْبِهِ وَزْنُ دِينَارٍ مِنَ الإِيمَانِ

ثُمَّ مَنْ كَانَ فِي قَلْبِهِ وَزْنُ نِصْفِ دِينَارٍ

ثُمَّ مَنْ كَانَ فِي قَلْبِهِ مِثْقَالُ حَبَّةٍ مِنْ خَرْدَلٍ

قَالَ أَبُو سَعِيدٍ فَمَنْ لَمْ يُصَدِّقْ هَذَا فَلْيَقْرَأْ

It was narrated that Abu Sa’īd al-Khudrī said, “The Messenger of Allah ﷺ said:

When Allah has saved the believers from Hell and they are safe, none of you will dispute with his companion more vehemently for some right of his in this world than the believers will dispute with their Lord on behalf of their brothers in faith who have entered Hell. They will say: “Our Lord! They are our brothers, they used to pray with us, fast with us and perform Hajj with us, and you have admitted them to Hell.” He will say: “Go and bring forth those whom you recognize among them.” So they will come to them, and they will recognize them by their faces. The Fire will not consume their faces, although there will be some whom the Fire will seize halfway up their shins, and others whom it will seize up to their ankles. They will bring them forth, and will say, “Our Lord, we have brought forth those whom You commanded us to bring forth.” Then He will say: “Bring forth those who have a dinar’s (a small coin) weight of faith in their hearts, then those who have half a dinar’s weight in their hearts than those who have a mustard-seed’s weight.”

Abu Sa’īd said, “He who does not believe this, let him recite,

إِنَّ اللَّهَ لاَ يَظْلِمُ مِثْقَالَ ذَرَّةٍ وَإِنْ تَكُ حَسَنَةً يُضَاعِفْهَا وَيُؤْتِ مِنْ لَدُنْهُ أَجْرًا عَظِيمًا

‘Surely, Allah wrongs not even of the weight of an atom, but is there is any good, He doubles it, and gives from Him a great reward’.” — Qur’an 4: 40
