الآية رقم (53) - وَيَقُولُ الَّذِينَ آمَنُواْ أَهَـؤُلاء الَّذِينَ أَقْسَمُواْ بِاللّهِ جَهْدَ أَيْمَانِهِمْ إِنَّهُمْ لَمَعَكُمْ حَبِطَتْ أَعْمَالُهُمْ فَأَصْبَحُواْ خَاسِرِينَ
(53) - (And those who believe will say, "Are these the ones who swore by Allah their strongest oaths that indeed they were with you?" Their deeds have become worthless, and they have become losers.)
The hypocrite, because of his severe hypocrisy, wants to obfuscate and cover up his double standards, so he swears by Allah that he is with the believers, so those who believe will say: Are these those who swore to Allah (swt) with their strongest oaths? So they became losers when they were revealed.
