Surah Ali 'Imran — Ayah 176 (3:176)
وَلَا يَحۡزُنكَ ٱلَّذِينَ يُسَٰرِعُونَ فِي ٱلۡكُفۡرِۚ إِنَّهُمۡ لَن يَضُرُّواْ ٱللَّهَ شَيۡـٔٗاۚ يُرِيدُ ٱللَّهُ أَلَّا يَجۡعَلَ لَهُمۡ حَظّٗا فِي ٱلۡأٓخِرَةِۖ وَلَهُمۡ عَذَابٌ عَظِيمٌ ١٧٦
English translation (Saheeh International)
And do not be grieved, [O Muḥammad], by those who hasten into disbelief. Indeed, they will never harm Allāh at all. Allāh intends that He should give them no share in the Hereafter, and for them is a great punishment.
Brief commentary
Do not sorrow, O Messenger, because of those hypocrites who rush to disbelief, turning on their heels. They do not harm Allah in any way, but only harm themselves by distancing themselves from faith in Allah and from doing as He instructs. Allah wills their defeat and failure, and that they will have no portion of bliss in the Afterlife: they will have a great punishment in the fire of Hell.
