إِنَّ الدِّينَ عِنْدَ اللَّهِ الْإِسْلَامُ.
Indeed, the religion accepted with Allah is Islam. (Āl ʿImrān 3:19)
ʿInda Allāh (“with Allah”) identifies the decisive criterion: the religion that is true and accepted by Allah is Islam. Truth is not established merely by the competing claims of religious adherents.
The verse states the basis of religious acceptance. Muslims hold to this revealed teaching and practice their religion accordingly.
