QS. Al-Ma'idah [5:53]

wayaquulu alladziina aamanuu ahaa‑ulaa‑i alladziina aqsamuu billaahi jahda aymaanihim innahum lama'akum habithat a'maaluhum fa‑ashbahuu khaasiriina

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. [53]
