Ahmed Raza Khan: Mohammed Aqib Qadri:
And had Allah willed, He could have made them all upon one religion, but He admits whomever He wills into His mercy; and the unjust do not have any friend nor any supporter.

Yusuf Ali:
If Allah had so willed, He could have made them a single people; but He admits whom He will to His Mercy; and the Wrong-doers will have no protector nor helper.

Pickthal:
Had Allah willed, He could have made them one community, but Allah bringeth whom He will into His mercy. And the wrong-doers have no friend nor helper.
