Narrated Anas bin Malik (Radi-Allahu ‘anhu):
The Prophet (Sallallahu ‘Alaihi Wa Sallam) said, “Allah has appointed an
angel in the womb, and the angel says, ‘O Lord! A drop of discharge (i.e.
of semen), O Lord! a clot, O Lord! a piece of flesh.’ And then, if Allah
wishes to complete the child’s creation, the angel will say. ‘O Lord! A
male or a female? O Lord! wretched or blessed (in religion)? What will his
livelihood be? What will his age be?’ The angel writes all this while the
child is in the womb of its mother.”
