﴿ فَإِذَا سَوَّيْتُهُۥ وَنَفَخْتُ فِيهِ مِن رُّوحِى فَقَعُوا۟ لَهُۥ سَٰجِدِينَ ﴾

“and when I have formed him fully and breathed into him of My spirit, fall down before him in prostration!”

So when I have proportioned him completed him and breathed caused to flow of My Spirit in him so that he becomes a living thing — the annexation of ‘the Spirit’ to him is a conferring of honour upon Adam — fall down in prostration before him!’ a prostration meant as an act of salutation by bowing.
