So, Allah-azwj Replied: ‘If I-azwj were to Send a Prophet-saww in the image of an angel, you would not be able to see him-saww (Quran – 25:7, 21:8).’ And Allah-azwj also Said: ‘There has come to you from Allah, Noor (a Light – The Prophet) and a Clarifying Book [5:15].’ In the Book, Allah-azwj has used the word Noor (Light) as a metaphor for guidance, which Allah-azwj Propagated through -saww.
By doing so, one would be questioning the Power of Allah-azwj, Who is able to Make them (angels/Prophets) to appear in the outfit of a human body. The responsibility of a believer is to respect the Guides from Allah-azwj and follow the Revealed Commands as being transmitted through them-as. Believers have been told (Holy Quran) not to ask for that which does not concern them.
As an inferior form of living being (as humans are tainted with sins), we cannot comprehend the status of a Prophet-as nor his-as successor – and -saww is the chief of Prophets-as.
