The Romans - 30:20 It is one of His signs that He created you from a dust and then you became mankind, spreading out and multiplying.
He began the creation of man from clay, then continued from semen:
The Prostration/32:7 He has perfected everything He created. He began the creation of man from clay.
The Prostration/32:8 Then He made his descendants descend from water of inferiority.
