Whatever you (O Muhammad SAW) may be doing, and whatever portion you may be reciting from the Quran, - and whatever deed you (mankind) may be doing (good or evil), We are Witness thereof, when you are doing it. And nothing is hidden from your Lord (so much as) the weight of an atom (or small ant) on the earth or in the heaven. Not what is less than that or what is greater than that but is (written) in a Clear Record. (Tafsir At-Tabari. Vol. 11, Page 129).
