whenever a plague fell upon them they would say o moses invoke your lord for us by the covenant he has made with you. if you remove the plague from us we will certainly believe in you and let the children of israel go along with you.
ولما وقع عليهم الرجز قالوا يا موسى ادع لنا ربك بما عهد عندك لئن كشفت عنا الرجز لنؤمنن لك ولنرسلن معك بني إسرائيل
