26:3
لَعَلَّكَ بَـٰخِعٌ نَّفْسَكَ أَلَّا يَكُونُوا۟ مُؤْمِنِينَ
laʿallaka bākhiʿun nafsaka allā yakūnū mu'minīna
[Prophet], are you going to worry yourself to death because they will not believe?
It may be that you (O Muhammad صلى الله عليه وسلم) are going to kill yourself with grief, that they do not become believers [in your Risalah (Messengership) i.e. in your Message of Islâmic Monotheism].
