Laakinil laahu yashhadu bimaaa anzala ilaika anzalahoo bi'ilmihee wal malaaa'ikatu yashhadoon; wa kafaa billaahi Shaheeda
But Allah bears witness to that which He has revealed to you. He has sent it down with His knowledge, and the angels bear witness [as well]. And sufficient is Allah as Witness.
1 Mufti Taqi Usmani
But Allah bears witness that what He has revealed to you, has revealed it with His knowledge. The angels too, bear witness, (though) Allah is sufficient as witness.
