الاعراف — Al-A'raf Ayat 135
فَلَمَّا كَشَفْنَا عَنْهُمُ الرِّجْزَ اِلٰٓى اَجَلٍ هُمْ بَالِغُوْهُ اِذَا هُمْ يَنْكُثُوْنَ
Falammā kasyafnā ‘anhumur-rijza ilā ajalin hum bāligūhu iżā hum yankuṡūn(a).
"But when We removed the punishment from them until a term which they were to reach, then at once they broke their word."
