whenever a plague struck them they would say moses pray to your lord for us by virtue of the promise he has made to you if you remove this plague from us we will surely believe in you and let the children of israel go 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
