(Al-Hijr) 15 : 29
فَإِذَا سَوَّيْتُهُ وَنَفَخْتُ فِيهِ مِنْ رُوحِي فَقَعُوا لَهُ سَاجِدِينَ
“And when I have proportioned him and breathed into him of My Spirit, then you fall to him in prostration".
This verse is repeated in verse 38: 72. The Spirit (Rooh) contains both soul and life. Every creature’s spirit including Jesus’ is from Lord Allah as explained in verse 4: 171. The sleep is a small death where the soul only departs, whereas in death the Spirit (soul plus life) will be departed as explained in verse 6: 60. See explanation 2: 28 and 4: 1.
