each time a scourge struck them they said o moses! pray for us to your lord on the strength of the prophethood he has bestowed upon you. surely if you remove this scourge from us we will truly believe in you and will 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
