Surah Al-Hajj (The Pilgrimage), Verse 10

ذٰلِكَ بِمَا قَدَّمَتْ یَدٰكَ وَاَنَّ اللّٰهَ لَیْسَ بِظَلَّامٍ لِّلْعَبِیْدِ 

Zaalika bimaa qaddamat yadaaka wa annal laaha laisa bizallaamil lil'abeed

“(It will be said): "This is because of the deeds which thy hands sent forth, for verily Allah is not unjust to His servants.”
