Abdullah ibn Mas’ud reported: The Messenger of Allah, peace and blessings be upon him, narrated to us, for he is truthful and trusted, “Verily, the creation of each one of you is brought together in his mother’s womb for forty days as a drop, then he is a clot for a similar period, then a morsel for a similar period, then there is sent to him the angel who blows the spirit into him and he is commanded regarding four matters: to write down his provision, his life span, his deeds, and whether he is blessed or damned. By Allah, other than whom there is no God, one of you acts like the people of Paradise until he is but an arm’s length from it and what is written overtakes him, so he acts like the people of Hellfire and he enters it. Verily, one of you acts like the people of Hellfire until he is but an arm’s length from it and what is written overtakes him, so he acts like the people of Paradise and he enters it.”
