﴿ أَمْ أَنَا۠ خَيْرٌۭ مِّنْ هَٰذَا ٱلَّذِى هُوَ مَهِينٌۭ وَلَا يَكَادُ يُبِينُ ﴾

“Am I not better than this contemptible man who can hardly make his meaning clear?”

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.
