﴿ قُلْ أَتُعَلِّمُونَ ٱللَّهَ بِدِينِكُمْ وَٱللَّهُ يَعْلَمُ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ ۚ وَٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمٌۭ ﴾

“Say: “Do you, perchance, [want to] inform God of [the nature of] your faith although God knows all that is in the heavens and all that is on earth? Indeed, God has full knowledge of every­thing!””
