وَیَقُوْلُ الَّذِیْنَ اٰمَنُوْۤا اَهٰۤؤُلَآءِ الَّذِیْنَ اَقْسَمُوْا بِاللّٰهِ جَهْدَ اَیْمَانِهِمْ اِنَّهُمْ لَمَعَكُمْ حَبِطَتْ اَعْمَالُهُمْ فَاَصْبَحُوْا خٰسِرِیْنَ ۟

Wa yaqoolul lazeena aamanooo ahaaa'ulaaa'il lazeena aqsamoo billaahi jahda aimaanihim innahum lama'akum; habitat a'maaluhum fa asbahoo khaasireen

“And those who believe will say: "Are these the men who swore their strongest oaths by Allah, that they were with you?" All that they do will be in vain, and they will fall into (nothing but) ruin.”
