Messenger of Allah, the truthful and trusted, may Allah's peace and blessings be upon him, his family and his companions, told us: "Each of you has been created in your mothers' wombs.
Forty days, like a seed, then the same length of time, like a hanging lump and then as a chewed piece of meat in less time. Then the angel sent down and blow in spirit of life and may be ordered to write down these four: living, life, deeds and if the child in the next life will be one of the lucky or unlucky.
If, in addition there is no god! Some of you will behave like those go to Paradise until it is just an arm's length between them and Paradise. Then what already has been written to take the upper hand and they will behave like those who come to hell and end up there.
Others will behave like those who come to Hell, until it is just an arm's length between them and Hell. Then what has already been written to take the upper hand and they will behave like those who come to paradise and end up there. "
