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.  

النَّبِيَّ ﷺ قَالَ يَدْخُلُ الْمَلَكُ عَلَى النُّطْفَةِ بَعْدَ مَا تَسْتَقِرُّ فِي الرَّحِمِ بِأَرْبَعِينَ أَوْ خَمْسَةٍ وَأَرْبَعِينَ لَيْلَةً فَيَقُولُ يَا رَبِّ أَشَقِيٌّ أَوْ سَعِيدٌ فَيُكْتَبَانِ فَيَقُولُ أَىْ رَبِّ أَذَكَرٌ أَوْ أُنْثَى فَيُكْتَبَانِ وَيُكْتَبُ عَمَلُهُ وَأَثَرُهُ وَأَجَلُهُ وَرِزْقُهُ ثُمَّ تُطْوَى الصُّحُفُ فَلاَ يُزَادُ فِيهَا وَلاَ يُنْقَصُ

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. (Using translation from Muslim 2644)   

عَنِ النَّبِيِّ ﷺ قَالَ يَدْخُلُ الْمَلَكُ عَلَى النُّطْفَةِ بَعْدَمَا تَسْتَقِرُّ فِي الرَّحِمِ أَرْبَعِينَ أَوْ خَمْسًا وَأَرْبَعِينَ لَيْلَةً فَيَقُولُ أَيْ رَبِّ أَشَقِيٌّ أَمْ سَعِيدٌ؟ فَيَقُولُ اللهُ ﷻ وَيَكْتُبانِ أَذَكَرٌ أَمْ أُنْثَى؟ فَيَقُولُ اللهُ وَيَكْتُبَانِ مُصِيبَتَهُ وَأَثَرَهُ وَرِزْقَهُ وَأَجَلَهُ ثُمَّ تُطْوَى الصَّحِيفَةُ فَلَا يُزَادُ فِيهَا أَوْ يُنْقَصُ مِنْهَا  

[Machine] The Prophet ﷺ said, "The angel is entrusted with the sperm after it settles in the womb for forty days or forty-five nights. Then he asks, 'O Lord, will it be miserable or happy?' And Allah replies, 'It will be written.' Then he asks, 'O Lord, will it be a male or a female?' And Allah replies, 'It will be written.' Then its deeds, lifespan, provisions, and influence are recorded. After that, the sheets are raised and nothing is added or subtracted from it."  

النَّبِيَّ ﷺ قَالَ يُوَكَّلُ الْمَلَكُ عَلَى النُّطْفَةِ بَعْدَ مَا تَسْتَقِرُّ فِي الرَّحِمِ أَرْبَعِينَ يَوْمًا أَوْ خَمْسًا وَأَرْبَعِينَ لَيْلَةً فَيَقُولُ أَيْ رَبِّ مَاذَا أَشَقِيٌّ أَوْ سَعِيدٌ؟ فَيَقُولُ اللهُ ﷻ فَيُكْتَبَانِ ثُمَّ يَقُولُ أَيْ رَبِّ ذَكَرٌ أَمْ أُنْثَى؟ فَيَقُولُ اللهُ ﷻ فَيُكْتَبَانِ فَيُكْتَبُ عَمَلُهُ وَأَجَلُهُ وَرِزْقُهُ وَأَثَرُهُ ثُمَّ تُرْفَعُ الصُّحُفُ فَلَا يُزَادُ فِيهَا وَلَا يُنْقَصُ  

"يَدْخُلُ الْمَلَكُ عَلَى النُّطْفَةِ بَعْدَ مَا تَسْتَقِر فِى الرَّحِم بِأَرْبَعِينَ لَيْلَةً فَيَقُولُ: يَا رَبِّ: مَاذَا؟ أَشَقِىٌّ أَمْ سَعِيدٌ؟ يَقُولُ اللَّه، وَيَكْتُبَان، أَذَكَرٌ أَمْ أُنْثَى؟ فَيَقُولُ اللَّه، وَيَكْتُبَانِ، وَيُكْتَبُ عَمَلُهُ وَأَثَرُهُ وَمَعْصِيَتُه وَرِزْقُهُ وَأَجَلُهُ، ثُمَّ تُطْوَى الصَّحِيفَةُ فَلَا يُزَادُ عَلَى مَا فِيهَا وَلَا يُنْقَصُ".
