سورة النمل

Ali ibn Ibrahim (may Allah have mercy on him): إِلَّا مَنْ ظَلَمَ [except one who has done wrong] means وَ لَا مَنْ ظَلَمَ [nor one who has done wrong], where the particle إلّا has been put in place of the particle لا.

Imam Ali (peace be upon him): As for the verses in whose outward form one word is used in place of another, this verse is an example: "...no believer is permitted to kill a believer, unless it be by mistake" (An-Nisa/92). Its meaning is وَ لَا خَطَأً [nor by mistake] — [the hamza has come in place of the waw and it became إلّا خطأً] — and likewise this saying of Allah: یا مُوسی لا تَخَفْ إِنِّی لا یَخافُ لَدَیَّ المُرْسَلُونَ؛ إِلَّا مَنْ ظَلَمَ ثُمَّ بَدَّلَ حُسْناً بَعْدَ سُوءٍ [O Musa, do not fear; indeed the messengers do not fear in My presence; except one who has done wrong, then substituted good after evil], the meaning of which is لَا مَنْ ظَلَمَ ثُمَّ بَدَّلَ حُسْناً بَعْدَ سُوءٍ [nor one who has done wrong, then substituted good after evil].
