Sahih Muslim, 6723

Rapporté par Abdullah (b. Mas’ud) : Le Messager d’Allah ﷺ, le plus véridique des hommes, a dit : « Voici comment se passe votre création : les éléments qui composent l’un d’entre vous sont rassemblés pendant quarante jours dans le ventre de sa mère sous forme de sperme, puis cela devient une adhérence de sang pendant une autre période de quarante jours. Ensuite, cela devient un morceau de chair, et quarante jours plus tard, Allah envoie un ange chargé d’écrire quatre choses : sa subsistance, sa mort, ses actions, son bonheur ou son malheur. Par Celui en dehors de qui il n’y a pas de divinité, l’un d’entre vous agit comme les gens du Paradis au point qu’il ne reste entre lui et le Paradis qu’une coudée, mais ce qui est écrit le rattrape et il commence à agir comme les gens de l’Enfer, et il y entre. Un autre agit comme les gens de l’Enfer jusqu’à ce qu’il ne reste entre lui et l’Enfer qu’une coudée, puis ce qui est écrit le rattrape et il commence à agir comme les gens du Paradis, et il y entre. »

Abdullah (b. Mas'ud) reported that Allah's Messenger (ﷺ) who is the most truthful (of the human beings) and his being truthful (is a fact) said:Verily your creation is on this wise. The constituents of one of you are collected for forty days in his mother's womb in the form of blood, after which it becomes a clot of blood in another period of forty days. Then it becomes a lump of flesh and forty days later Allah sends His angel to it with instructions concerning four things, so the angel writes down his livelihood, his death, his deeds, his fortune and misfortune. By Him, besides Whom there is no god, that one amongst you acts like the people deserving Paradise until between him and Paradise there remains but the distance of a cubit, when suddenly the writing of destiny overcomes him and he begins to act like the denizens of Hell and thus enters Hell, and another one acts in the way of the denizens of Hell, until there remains between him and Hell a distance of a cubit that the writing of destiny overcomes him and then he begins to act like the people of Paradise and enters Paradise
