GodlyVerses

The Prophet (ﷺ) said, "At every womb Allah appoints an angel who says, 'O Lord! A drop of semen, O
Lord! A clot. O Lord! A little lump of flesh." Then if Allah wishes (to complete) its creation, the angel
asks, (O Lord!) Will it be a male or female, a wretched or a blessed, and how much will his provision
be? And what will his age be?' So all that is written while the child is still in the mother's womb." - Hadith Al Bukhari 318 (islam)
Book 6, Hadith 23
Vol. 1, Book 6, Hadith 315

Allah's Messenger (ﷺ), the truthful and truly-inspired, said, "Each one of you collected in the womb of his
mother for forty days, and then turns into a clot for an equal period (of forty days) and turns into a
piece of flesh for a similar period (of forty days) and then Allah sends an angel and orders him to
write four things, i.e., his provision, his age, and whether he will be of the wretched or the blessed (in
the Hereafter). Then the soul is breathed into him. And by Allah, a person among you (or a man) may
do deeds of the people of the Fire till there is only a cubit or an arm-breadth distance between him and
the Fire, but then that writing (which Allah has ordered the angel to write) precedes, and he does the
deeds of the people of Paradise and enters it; and a man may do the deeds of the people of Paradise till
there is only a cubit or two between him and Paradise, and then that writing precedes and he does the
deeds of the people of the Fire and enters it." - Hadith Al Bukhari 6594 (islam)

Vol. 8, Book 77, Hadith 593

" The creation of any one of you is like this that (semen) is collected in the womb of the mother for forty nights," and in the hadith transmitted on the authority of Shu'ba (the words are):" Forty nights and forty days." And in the hadith transmitted on the authority of Jarir and 'Isa (the words are):" Forty days." - Hadith Muslim 2643b (islam)
Book 46, Hadith 2
Book 33, Hadith 6391

When the drop of (semen) remains in the womb for forty or forty five nights, the angel comes and says: My Lord, will he be good or evil? And both these things would be written. Then the angel says: My Lord, would he be male or female? And both these things are written. And his deeds and actions, his death, his livelihood; these are also recorded. Then his document of destiny is rolled and there is no addition to nor subtraction from it. - Hadith Muslim 2644 (islam)
Book 46, Hadith 3
Book 33, Hadith 6392

Evil one is he who is evil in the womb of his mother and the good one is he who takes a lesson from the (fate of) others. The narrator came to a person from amongst the Companions of Allah's Messenger (ﷺ) who was called Hudhaifa b. Usaid Ghifari and said: How can a person be an evil one without (committing an evil) deed? Thereupon the person said to him: You are surprised at this, whereas I have heard Allah's Messenger (ﷺ) as saying: When forty-two nights pass after the semen gets into the womb, Allah sends the angel and gives him shape. Then he creates his sense of hearing, sense of sight, his skin, his flesh, his bones, and then says: My Lord, would he be male or female? And your Lord decides as He desires and the angel then puts down that also and then says: My Lord, what about his age? And your Lord decides as He likes it and the angel puts it down. Then he says: My Lord, what about his livelihood? And then the Lord decides as He likes and the angel writes it down, and then the angel gets out with his scroll of destiny in his hand and nothing is added to it and nothing is subtracted from it. - Hadith Muslim 2645a (islam)
Book 46, Hadith 4
Book 33, Hadith 6393

I visited Abu Sariha Hudhaifa b. Usaid al-Ghifari who said: I listened with these two ears of mine Allahs Messenger (ﷺ) as saying: The semen stays in the womb for forty nights, then the angel, gives it a shape. Zubair said: I think that he said: One who fashions that and decides whether he would be male or female. Then he (the angel) says: Would his limbs be full or imperfect? And then the Lord makes thein full and perfect or otherwise as He desires. Then he says: My Lord, what about his livelihood, and his death and what about his disposition? And then the Lord decides about his misfortune and fortune. - Hadith Muslim 2645c (islam)
Book 46, Hadith 6
Book 33, Hadith 6395

Allah's Messenger (ﷺ), the true and truly inspired said, "(The matter of the Creation of) a human being is put
together in the womb of the mother in forty days, and then he becomes a clot of thick blood for a
similar period, and then a piece of flesh for a similar period. Then Allah sends an angel who is ordered
to write four things. He is ordered to write down his (i.e. the new creature's) deeds, his livelihood, his
(date of) death, and whether he will be blessed or wretched (in religion). Then the soul is breathed into
him. So, a man amongst you may do (good deeds till there is only a cubit between him and Paradise
and then what has been written for him decides his behavior and he starts doing (evil) deeds
characteristic of the people of the (Hell) Fire. And similarly a man amongst you may do (evil) deeds
till there is only a cubit between him and the (Hell) Fire, and then what has been written for him
decides his behavior, and he starts doing deeds characteristic of the people of Paradise." - Hadith Al Bukhari 3208 (islam)
