:salam2: my bros and sisses
There may be basically two reasons why I would think this reaction would be brought about.
1) Think about it this way, do you or anyone really know what an angel looks like? It's almost impossible to imagine. some aspects were told in the Qur'aan, but as to their entire being, we have no idea. Therefore, is it not a bit disrespectful to draw them especially? Since we KNOW we cannot get them absolutely right, and there are going to be wrong aspects of the picture???
We believe Angels are a part of the unseen. Which we have no knowledge of, therefore we should only take things we know if them as it is, and not make interpretations or guesses afterwards. It's like ... if you wanted to have a picture painted of yourself, would it be sufficient for you to call the painter up and say, "Yes, i'm 6 feet tall, brown hair, purple eyes, and like cats... please paint a picture of me!" ... would it? The painter doesnt really know who you are, therefore while drawing he would have to make guesses, add ons, changes, therefore... it's not YOU anymore is it? It's the painters creation simply on your description which is vague.
Also, if you think about it... if he painted such a picture and you came back to it, and it didn't look like you, would you be overjoyed or offended???
Offended most likely no? "WHAT? I dont look like that, that's twenty pounds heavier... where did those wrinkles come from, that nose is not mine!"
If you would be offended, as a mere human, think of some of the greatest subserviants to Allah... to God... ???
IS THAT NOT A GREATER OFFENSE??!
I think it is. Anyways, i have a second point, but no time... sorry... i hope you get better answers.
