Al-Anfal - 8:51

ذَلِكَ بِمَا قَدَّمَتْ أَيْدِيكُمْ وَأَنَّ اللّهَ لَيْسَ بِظَلاَّمٍ لِّلْعَبِيدِ
[8:51]
This is for what your own hands have sent on before, and because Allah is not in the least unjust to the servants;
"Because of (the deeds) which your (own) hands sent forth; for Allah is never unjust to His servants:
This is for that which your own hands have sent before (to the Judgment), and (know) that Allah is not a tyrant to His slaves.
