"When I have fashioned him in due proportions and breathed into him out of My Spirit, then fall down prostrating before him (as a token of respect for him and his superiority)."
And when I have perfected him in due proportion and breathed into him something of My Energy, bow before him." (That something will be the gift of free will, the ability to make decisions (76:3))
"So, when I have fashioned him (Adam, the first man) in the his proper measures and breathed into him (Adam), the soul that I (Allah) created for him, then you (angels) fall down prostrate (in a show of respect) for him."
So when I accomplish the perfection of his (physical) constitution into his real being, and breathe My (divine) spirit into (the inner self of) this (human physical) organism, then fall down prostrate before him.
"So, when I have fashioned him completely and breathed into him (Adam) the soul which I created for him, then fall (you) down prostrating yourselves unto him."
“And when I have proportioned him (perfected his body and brain) and breathed into Him from my Spirit (the qualities denoted by my Names) prostrate to him (commence your servitude to him as his forces)!”
Sayyed Abbas Sadr-Ameli
So when I have completed him and I have breathed into him of My Spirit, fall you down, prostrating yourselves unto him
Al-muntakhab fi tafsir al-Qur'an al-Karim
And when I have fashioned it and furnished it with a definite shape and imparted to it My spirit, then prostrate yourselves to him in reverence and admiration
