﴿ 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 ‘God suffices as a witness between me and you of my sincerity. Truly He is Aware Seer of His servants’ Knower of what they hide and what they manifest.
