Surah Al-Hijr 15:29

فَإِذَا سَوَّيْتُهُۥ وَنَفَخْتُ فِيهِ مِن رُّوحِى فَقَعُوا۟ لَهُۥ سَـٰجِدِينَ

And when I have proportioned him and breathed into him of My [created] soul, then fall down to him in prostration."

Translation: Saheeh International

Tafsir

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.
