النَّبِيِّ صلى الله عليه وسلم قَالَ وَكَّلَ اللَّهُ بِالرَّحِمِ مَلَكًا فَيَقُولُ أَىْ رَبِّ نُطْفَةٌ، أَىْ رَبِّ عَلَقَةٌ، أَىْ رَبِّ مُضْغَةٌ. فَإِذَا أَرَادَ اللَّهُ أَنْ يَقْضِيَ خَلْقَهَا قَالَ أَىْ رَبِّ ذَكَرٌ أَمْ أُنْثَى أَشَقِيٌّ أَمْ سَعِيدٌ فَمَا الرِّزْقُ فَمَا الأَجَلُ فَيُكْتَبُ كَذَلِكَ فِي بَطْنِ أُمِّهِ .
The Prophet (ﷺ) said, "Allah puts an angel in charge of the uterus and the angel says, 'O Lord, (it is)semen! O Lord, (it is now ) a clot! O Lord, (it is now) a piece of flesh.' And then, if Allah wishes tocomplete its creation, the angel asks, 'O Lord, (will it be) a male or a female? A wretched (an evildoer) or a blessed (doer of good)? How much will his provisions be? What will his age be?' So all thatis written while the creature is still in the mother's womb."
