فَكَيْفَ إِذَا جِئْنَا مِن كُلِّ أُمَّةٍۭ بِشَهِيدٍۢ وَجِئْنَا بِكَ عَلَىٰ هَٰٓؤُلَآءِ شَهِيدًۭا
So how [will it be] when We bring from every nation a witness and we bring you, [O Muhammad] against these [people] as a witness?
Surely! Allah wrongs not even of the weight of a speck of dust, but if there is any good (done), He doubles it, and gives from Him a great reward (40)How (will it be) then, when We bring from each nation a witness and We bring you (O Muhammad) as a witness against these people (41)On that day those who disbelieved and disobeyed the Messenger will wish that they were buried in the earth, but they will never be able to hide a single fact from Allah (42)
Allah Wrongs Not Even the Weight of a Speck of Dust
Allah states that He does not treat any of His servants with injustice on the Day of Resurrection, be it the weight of a mustard seed or a speck of dust. Rather, Allah shall reward them for this action and multiply it, if it were a good deed. For instance, Allah said,
وَنَضَعُ الْمَوَازِينَ الْقِسْطَ
(And We shall set up balances of justice)[21:47] Allah said that Luqman said,
يَا بُنَيَّ إِنَّهَا إِن تَكُ مِثْقَالَ حَبَّةٍ مِّنْ خَرْدَلٍ فَتَكُن فِي صَخْرَةٍ أَوْ فِي السَّمَاوَاتِ أَوْ فِي الْأَرْضِ يَأْتِ بِهَا اللَّهُ
(O my son! If it be (anything) equal to the weight of a mustard seed, and though it be in a rock, or in the heavens or in the earth, Allah will bring it forth). [31:16] Allah said,
يَوْمَئِذٍ يَصْدُرُ النَّاسُ أَشْتَاتًا لِّيُرَوْا أَعْمَالَهُمْ - فَمَن يَعْمَلْ مِثْقَالَ ذَرَّةٍ خَيْرًا يَرَهُ - وَمَن يَعْمَلْ مِثْقَالَ ذَرَّةٍ شَرًّا يَرَهُ
(That Day mankind will proceed in scattered groups that they may be shown their deeds. So whosoever does good equal to the weight of a speck of dust shall see it. And whosoever does evil equal to the weight of a speck of dust shall see it.)[99:6-8]
The Two Sahihs recorded the long Hadith about the intercession that Abu Sa'id Al-Khudri narrated, and in which the Messenger of Allah ﷺ said,
فَيَقُولُ اللهُ عَزَّ وَجَلَّ: ارْجِعُوا، فَمَنْ وَجَدْتُمْ فِي قَلْبِهِ مِثْقَالَ حَبَّةِ خَرْدَلٍ مِنْ إِيمَانٍ، فَأَخْرِجُوهُ مِنَ النَّارِ
(Allah then says, "Go back, and take out of the Fire everyone in whose heart you find the weight of a mustard seed of faith") In another narration, Allah says,
وفي لفظ: أَدْنَى أَدْنَى أَدْنَى مِثْقَالِ ذَرَّةٍ مِنْ إِيمَانٍ، فَأَخْرِجُوهُ مِنَ النَّارِ، فَيُخْرِجُونَ خَلْقًا كَثِيرًا
("Whosoever had the least, least, least speck of faith, take him out of the Fire," and they will take out many people.) Abu Sa'id then said, "Read, if you will,
إِنَّ اللَّهَ لَا يَظْلِمُ مِثْقَالَ ذَرَّةٍ
(Surely! Allah wrongs not even of the weight of a speck of dust)."
Will Punishment be Diminished for the Disbelievers?
Sa'id bin Jubayr commented about Allah's statement,
وَإِن تَكُ حَسَنَةً يُضَاعِفْهَا
(but if there is any good (done), He doubles it,)
As for the disbeliever, his punishment will be lessened for him on the Day of Resurrection, but he will never depart the Fire. He used as evidence the authentic Hadith in which Al-'Abbas said, "O Messenger of Allah! Your uncle Abu Talib used to protect and support you, did you benefit him at all?" The Messenger ﷺ said,
نَعَمْ هُوَ فِي ضَحْضَاحٍ مِنْ نَارٍ، وَلَوْلَا أَنَا، لَكَانَ فِي الدَّرْكِ الْأَسْفَلِ مِنَ النَّارِ
(Yes. He is in a shallow area in Hell-fire, and were it not for me, he would have been in the …
