فَلَنَقُصَّنَّ عَلَيْهِم بِعِلْمٍ ۖ وَمَا كُنَّا غَآئِبِينَ
Commentary:
God’s purpose in questioning the Messengers and the people (7:7 above) would not be to gain information or supplement His knowledge,––for He is All-Knowing—but, on the contrary, to impress upon both parties the extent and perfection of His own knowledge. After the people and the Prophets will have said what they will have to say, God Himself will tell them in detail what they did and what they should have done but failed to do, and thus the all-comprehensiveness of God’s knowledge will be fully brought home to them.
