And Allah did create you (Adam) from dust, then from Nutfah (male and female discharge semen drops i.e. Adam's offspring), then He made you pairs (male and female). And no female conceives or gives birth, but with His Knowledge. And no aged man is granted a length of life, nor is a part cut off from his life (or another man's life), but is in a Book (AlLauh AlMahfuz) Surely, that is easy for Allah.
