﴿ قُلْ كَفَىٰ بِٱللَّهِ شَهِيدًۢا بَيْنِى وَبَيْنَكُمْ ۚ إِنَّهُۥ كَانَ بِعِبَادِهِۦ خَبِيرًۢا بَصِيرًۭا ﴾

“Say: "None can bear witness between me and you as God does: verily, fully aware is He of His creatures, and He sees all [that is in their hearts]."”

(Say) O Muhammad, to the people of Mecca: (Allah sufficeth for a witness between me and you) that I am a messenger to you (Lo! He is) in relation to sending messengers to His servants (Knower, Seer of His slaves) those who believe and those who do not.
