فَإِذَا سَوَّيۡتُهُۥ وَنَفَخۡتُ فِيهِ مِن رُّوحِى فَقَعُواْ لَهُۥ سَٰجِدِينَ
"When I have fashioned him (in due proportion) and breathed into him of My spirit, fall ye down in obeisance unto him."<br/>
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.
