Osluk yadaka fee jaybika takhruj baydaamin ghayri soo-in wadmum ilayka janahakamina arrahbi fathanika burhanani minrabbika ila firAAawna wamala-ihi innahum kanooqawman fasiqeen

Insert your hand into the opening of your garment; it will come out white, without disease. And draw in your arm close to you [as prevention] from fear, for those are two proofs from your Lord to Pharaoh and his establishment. Indeed, they have been a people defiantly disobedient."

Insert your hand into your bosom, and it will come out white without any evil (disease), and press your arm to your side for (removing) fear. Thus these are two proofs from your Lord (sent) to Pharaoh and his chiefs. Indeed they are transgressing people.”
