قُلۡ كَفَىٰ بِٱللَّهِ شَهِيدَۢا بَيۡنِي وَبَيۡنَكُمۡۚ إِنَّهُۥ كَانَ بِعِبَادِهِۦ خَبِيرَۢا بَصِيرٗا ٩٦
Say, "Sufficient is Allāh as Witness between me and you. Indeed He is ever, concerning His servants, Aware and Seeing."
Translation: Saheeh International (English)
Each word's meaning and sound
Say, O Messenger: Allah is sufficient as a witness between me and you that I am a Messenger was sent to you and that I have conveyed what I was sent to you. Surely, He encompasses the conditions of His servants, nothing of them being hidden from Him, and He sees all the secrets of their souls.
