`Sayyiduna Hudhayfah bin Asid (may Allah be pleased with him) narrates from the Messenger of Allah (peace and blessings be upon him) that` when the drop of fluid remains in the womb for forty or forty-five nights, an angel comes to it and says, "O Lord! Should I write him as wretched or blessed?" Then whatever Allah commands, he writes it as such. Then he says, "Should I write him as male or female?" Then whatever Allah commands, he writes it as such, and he writes his deeds, his effect, his lifespan, and his provision. Then the record is rolled up; nothing is added to it nor subtracted from it.
