وَإِن كَذَّبُوكَ فَقُل لِّي عَمَلِي وَلَكُمْ عَمَلُكُمْ ۖ أَنتُم بَرِيئُونَ مِمَّا أَعْمَلُ وَأَنَا بَرِيءٌ مِّمَّا تَعْمَلُونَ (41)
(10:41) And if they reject you as false, tell them: 'My deeds are for myself and your deeds for yourselves. You will not be held responsible for my deeds, nor I for your deeds. *49
*49). Since every individual is himself accountable for his deeds, there is no point in engaging in unnecessary discussions which are often actuated by obduracy. For if the Prophet (peace be on him) was indeed inventing lies, he would bear the evil consequence of such an action. On the other hand, if his opponents were denying the truth, their action will not hurt the Prophet (peace be on him), but rather hurt themselves.
