﴿ فَلَمَّا كَشَفْنَا عَنْهُمُ ٱلْعَذَابَ إِذَا هُمْ يَنكُثُونَ ﴾

“But whenever We removed the suffering from them, lo! they would break their word.”

(But when We eased them of the torment) when We removed the torment from them, (behold! they broke their word) they broke their undertaking and refused to believe.
