وَيَضِيقُ صَدۡرِى وَلَا يَنطَلِقُ لِسَانِى فَأَرۡسِلۡ إِلَىٰ هَٰرُونَ
"My breast will be straitened. And my speech may not go (smoothly): so send unto Aaron.<br/>
and that anguish will constrain my breast, because of their denial of me, and that my tongue will not utter clearly, to deliver the Message, because of the knot in it. So give the Mission to, my brother, Aaron, alongside me.
