18:6
فَلَعَلَّكَ بَٰخِعٌۭ نَّفْسَكَ عَلَىٰٓ ءَاثَٰرِهِمْ إِن لَّمْ يُؤْمِنُوا۟ بِهَٰذَا ٱلْحَدِيثِ أَسَفًا
Fala'allaka baakhi'un nafsaka 'alaaa aasaarihim illam yu;minoo bihaazal hadeesi asafaa
(O Muhammad), if they do not believe in this Message, you will perhaps torment yourself to death with grief, sorrowing over them.
