Sura al-Māʾidah 5:53

وَيَقُولُ ٱلَّذِينَ ءَامَنُوٓا۟ أَهَٰٓؤُلَآءِ ٱلَّذِينَ أَقْسَمُوا۟ بِٱللَّـهِ جَهْدَ أَيْمَٰنِهِمْ إِنَّهُمْ لَمَعَكُمْ حَبِطَتْ أَعْمَٰلُهُمْ فَأَصْبَحُوا۟ خَٰسِرِينَ

wayaqūlu lladhīna āmanū a-hāʾulāʾi lladhīna aqsamū billāhi jahda aymānihim innahum lamaʿakum ḥabiṭat aʿmāluhum fa-aṣbaḥū khāsirīna

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.
