So (it was)!And We knew all about him.Mujahid and As-Suddi said,"This means that Allah knew everything about him and his army, and nothing was hidden from Him, even though they came from so many different nations and lands. For,لَا يَخْفَى عَلَيْهِ شَىْءٌ فِي الااٌّرْضِ وَلَا فِى السَّمَأءِTruly, nothing is hidden from Allah, in the earth or in the heaven. (3:5)
