The Holy Quran 4:166 — Surah An-Nisa
Arabic text
لَّـٰكِنِ ٱللَّهُ يَشْهَدُ بِمَآ أَنزَلَ إِلَيْكَ ۖ أَنزَلَهُۥ بِعِلْمِهِۦ ۖ وَٱلْمَلَـٰٓئِكَةُ يَشْهَدُونَ ۚ وَكَفَىٰ بِٱللَّهِ شَهِيدًا
Translation
Nevertheless, Allaah Himself testifies to (the truth of) that which He revealed to you (O Muhammad ﷺ). He revealed it with full knowledge (revealed the complete message) and the angels also testify. (Even if the testimony of the angels was not there,) Allaah is enough as a Witness.
