How sound is the statement that "he frowned and turned away" refers to Umar ibn al-Khattab, not the Messenger, may Allah bless him and grant him peace, based on the argument that verses addressed to the Messenger come in the second person, such as "you frowned and turned away," and that the Messenger was of a noble character and an excellent role model?

The exegetes have unanimously agreed that the reason for the revelation of Surat "Abasa" (He Frowned) concerned the Prophet, peace be upon him, and Abdullah ibn Umm Maktum. The Prophet, peace be upon him, was inviting the chieftains of Quraish to Islam when Ibn Umm Maktum, who was blind, approached him repeatedly with questions. The Prophet, peace be upon him, disliked his interruption and turned away from him, hoping for the conversion of Quraish. Thereupon, the verses were revealed, reprimanding him.

Allah Almighty addressed the Prophet using the third-person style ("He frowned and turned away") to glorify and honor him, then shifted to direct address ("And what would make you know") to comfort him.

The Prophet, peace be upon him, used to honor Ibn Umm Maktum, saying to him, "Welcome to the one concerning whom my Lord reprimanded me." He also appointed him as his deputy in Medina several times. The fact that the Prophet, peace be upon him, frowned in this situation does not contradict his excellent character, for he is a human being subject to the same experiences as other human beings. This incident is evidence of his truthfulness and that he did not conceal anything of what was revealed to him. And Allah knows best.
