أَفَمَن كَانَ مُؤْمِنًا كَمَن كَانَ فَاسِقًا ۚ لَّا يَسْتَوُونَ (18)
(32:18) Would a true believer be like him who was an evil-doer? *30 Surely they are not equal. *31
*30) Here mu min (believer) and Fasiq (sinner) have been used as two contrasting terms. Mu 'min is he who believes in Allah as his Lord and the One and only Deity and adopts obedience of the Law which AIlah has sent down through His Prophets. Contrary to this, Fasiq is he who adopts the attitude of fisq (disobedience, rebellion, independence and obedience to others than Allah).
*31) That is, "They can neither have the same way of thinking and life in the world nor can they be treated alike by God in the Hereafter."
