CAMan77555: Many Muslims strongly oppose the Christian practice of worshipping Jesus. They contend that God is but one, and that He alone is to be worshipped. Man is not to bow down to any other creature; to do so is to commit "shirk" - a most terrible sin for any Muslim!

RKC: It’s the most terrible sin to worship something besides or with The Father.

CAMan77555: Despite this strong objection to the worship of any creature other than God, the Qur'an itself relates an account of God Himself commanding His angels to bow down and worship something other than Him. He commanded them to bow before Adam!

And behold, We (God) said to the angels: "Bow down to Adam."
Surat-ul Baqara (2):34

Behold! Thy Lord said to the angels: "I am about to create man, from sounding clay, from mud molded into shape. When I have fashioned him and breathed into him of my spirit, fall ye down in obeisance unto him."
Surat-ul Hijr (15):28-30

RKC: This bowing down was a sign of respect, not worship. They were commanded to bow down to acknowledge the free will and higher status of man.
