(Isra) 17 : 96
قُلْ كَفَىٰ بِاللَّهِ شَهِيدًا بَيْنِي وَبَيْنَكُمْ ۚ إِنَّهُ كَانَ بِعِبَادِهِ خَبِيرًا بَصِيرًا
You say: "Sufficient is Lord Allah as Witness between you and me; indeed enough is your Lord to acquaint and observe upon His servants”.
See explanation 13: 43; 16: 43-44 and 17: 17 and 30.
