Allah warns you so that you never repeat the like of it again, if you are believers!
Sayyed Abbas Sadr-Ameli
Allah admonishes you that you should never repeat the like of it for ever, if you are (true) believers
Al-muntakhab fi tafsir al-Qur'an al-Karim
Allah exhorts you not to reiterate such vile conduct ever if indeed you believe in Him with hearts imprinted with the image of religious and spiritual virtues
