Fussilat • EN-TAFSIR-IBN-ABBAS
﴿ مَّنْ عَمِلَ صَٰلِحًۭا فَلِنَفْسِهِۦ ۖ وَمَنْ أَسَآءَ فَعَلَيْهَا ۗ وَمَا رَبُّكَ بِظَلَّٰمٍۢ لِّلْعَبِيدِ ﴾
“WHOEVER does what is just and right, does so for his own good; and whoever does evil, does so to his own hurt: and never does God do the least wrong to His creatures.”
(Whoso doeth right) sincerely between him and his Lord (it is for his soul) the reward of that is for his soul, (and whoso doeth wrong it is against it) and whosoever associates partners with Allah, the punishment of this associationism will be against his own soul. (And thy Lord) O Muhammad (is not at all a tyrant to His slaves) such that He would punish them for no crime.
