The Prophet being reprimanded because He frowned at a Weak Man
More than one of the scholars of Tafsir mentioned that one day the Messenger of Allah was addressing one of the great leaders of the Quraysh while hoping that he would accept Islam. While he was speaking in direct conversation with him, Ibn Umm Maktum came to him, and he was of those who had accepted Islam in its earliest days. He (Ibn Umm Maktum) then began asking the Messenger of Allah about something, urgently beseeching him. The Prophet hoped that the man would be guided, so he asked Ibn Umm Maktum to wait for a moment so he could complete his conversation. He frowned in the face of Ibn Umm Maktum and turned away from him in order to face the other man. Thus, Allah revealed,
عَبَسَ وَتَوَلَّى
أَن جَاءهُ الاَْعْمَى
