Say, "Sufficient is Allah as Witness between me and you. Indeed he is ever, concerning His servants, Acquainted and Seeing."  

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.
القرآن:١٧:٩٦ –

قُلْ كَفَىٰ بِاللَّهِ شَهِيدًا بَيْنِي وَبَيْنَكُمْ ۚ إِنَّهُ كَانَ بِعِبَادِهِ خَبِيرًا بَصِيرًا  

{قل كفى بالله شهيدا بيني وبينكم} على صدقي {إنه كان بعباده خبيرا بصيرا} عالما ببواطنهم وظواهرهم.
