Surah An-Nisa' (The Women), Verse 166

لٰكِنِ اللّٰهُ یَشْهَدُ بِمَاۤ اَنْزَلَ اِلَیْكَ اَنْزَلَهٗ بِعِلْمِهٖ وَالْمَلٰٓىِٕكَةُ یَشْهَدُوْنَ وَكَفٰی بِاللّٰهِ شَهِیْدًا ۟

Laakinil laahu yashhadu bimaaa anzala ilaika anzalahoo bi'ilmihee wal malaaa'ikatu yashhadoon; wa kafaa billaahi Shaheeda

“But Allah beareth witness that what He hath sent unto thee He hath sent from His (own) knowledge, and the angels bear witness: But enough is Allah for a witness.”
