الكهف — Al-Kahf Ayat 6

فَلَعَلَّكَ بَاخِعٌ نَّفْسَكَ عَلٰٓى اٰثَارِهِمْ اِنْ لَّمْ يُؤْمِنُوْا بِهٰذَا الْحَدِيْثِ اَسَفًا

Fa la‘allaka bākhi‘un nafsaka ‘alā āṡārihim illam yu'minū bihāżal-ḥadīṡi asafā(n).

"Then perhaps you would kill yourself through grief over them, [O Muhammad], if they do not believe in this message, [and] out of sorrow."
