The Victory - 48:28
He is the One Who sent His Messenger with guidance and the true religion, to make it superior to all religions. Allah is sufficient as a witness.
Allah will make His religion superior to all religions:
The Light/24:55
Allah has promised those of you who believe and do righteous deeds that He will make them sovereign as He made those before them sovereign, and establish for them the religion He has chosen for them, and turn their fear into security. For they serve me and associate nothing in common with me. Those who disbelieve after that are those who have gone astray.
The Ranks/61:8
They seek to extinguish the light of Allah with their mouths. Allah will complete His light even if the disbelievers dislike it.
The Ranks/61:9
He has sent His messenger with guidance and the true religion so that He may make it superior to all religions, even if those who associate partners dislike it.
The Forgiver/40:14
Serve Allah alone in religion, even if the disbelievers dislike it.
