An-Nisaa 4:47

O you who were given the Scripture, believe in what We have sent down [to Muhammad] – confirming your own Scriptures – before We obliterate faces turning them backward, or We curse them[33] as We cursed the Sabbath-breakers. For Allah’s will is always executed.

O you who were given the Scripture, believe in what We have sent down [to Prophet Muḥammad (ﷺ)], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers.[192] And ever is the matter [i.e., decree] of Allāh accomplished.

[192] See 7:163-166.

47. O you who have been given the Scripture (Jews and Christians)! Believe in what We have revealed (to Muhammad صلى الله عليه وسلم) confirming what is (already) with you, before We efface faces (by making them like the back of necks; without nose, mouth) and turn them hindwards, or curse them as We cursed the Sabbath-breakers[16]. And the Commandment of Allâh is always executed.[17]
