﴿ وَوُفِّيَتْ كُلُّ نَفْسٍۢ مَّا عَمِلَتْ وَهُوَ أَعْلَمُ بِمَا يَفْعَلُونَ ﴾

“for every human being will be repaid in full for whatever [good or evil] he has done: and He is fully aware of all that they do.”

And every soul will be paid in full for what it did that is it will be paid the requital thereof and He is best aware of what they do and has no need for any witnesses.
