فَكَفَى بِاللّهِ شَهِيدًا بَيْنَنَا وَبَيْنَكُمْ إِن كُنَّا عَنْ عِبَادَتِكُمْ لَغَافِلِينَ
[10:29]
Therefore Allah is sufficient as a witness between us and you that we were quite unaware of your serving (us).
"Enough is Allah for a witness between us and you: we certainly knew nothing of your worship of us!"
Allah sufficeth as a witness between us and you, that we were unaware of your worship.
