Verš 43:52

Což nejsem lepší než tenhle opovržený, jenž sotva vyjádřit se umí?

Tafsir al-Jalalayn

Or, do you perceive, in which case, am I not better than this one, namely, Moses, who is contemptible, feeble and lowly, and who can scarcely speak clearly?, [who can scarcely] articulate his speech, because of his lisp — which was the result of his [accidentally] placing a hot coal in his mouth when he was a child.
