Ash-Shu'ara' - 26:3

لَعَلَّكَ بَاخِعٌ نَّفْسَكَ أَلَّا يَكُونُوا مُؤْمِنِينَ
[26:3]
Perhaps you will kill yourself with grief because they do not believe.
It may be thou frettest thy soul with grief, that they do not become Believers.
It may be that thou tormentest thyself (O Muhammad) because they believe not.
