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.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ بِأُذُنَىَّ هَاتَيْنِ يَقُولُ إِنَّ النُّطْفَةَ تَقَعُ فِي الرَّحِمِ أَرْبَعِينَ لَيْلَةً ثُمَّ يَتَصَوَّرُ عَلَيْهَا الْمَلَكُ قَالَ زُهَيْرٌ حَسِبْتُهُ قَالَ الَّذِي يَخْلُقُهَا فَيَقُولُ يَا رَبِّ أَذَكَرٌ أَوْ أُنْثَى فَيَجْعَلُهُ اللَّهُ ذَكَرًا أَوْ أُنْثَى ثُمَّ يَقُولُ يَا رَبِّ أَسَوِيٌّ أَوْ غَيْرُ سَوِيٍّ فَيَجْعَلُهُ اللَّهُ سَوِيًّا أَوْ غَيْرَ سَوِيٍّ ثُمَّ يَقُولُ يَا رَبِّ مَا رِزْقُهُ مَا أَجَلُهُ مَا خُلُقُهُ ثُمَّ يَجْعَلُهُ اللَّهُ شَقِيًّا أَوْ سَعِيدًا  

[Machine] "The miserable is the one who is miserable in his mother's womb, and the fortunate is the one who is advised by others. He said, 'From which of these did you wonder?' I said, 'Is anyone miserable without doing any actions?' So, he leaned with his hands on his ears and said, 'I heard the Messenger of Allah, ﷺ , with these two ears of mine saying, "The sperm fertilizes in the womb for forty nights, then it becomes a clinging clot for a similar period, then it becomes a lump of flesh for a similar period. At that time, Allah’s appointed angels come to it and they ask, "O Lord, is it a male or a female?" And your Lord decides and then the angels ask, "O Lord, would it be blessed or wretched?" And your Lord decides regarding this matter. Then the angels ask, "O Lord, what is its fate and what is its provision?" And your Lord decides regarding this matter. Then the angel records the provision that he will be provided with, whether he would be happy or miserable.'"  

أَنَّ الشَّقِيَّ مَنْ شَقِيَ فِي بَطْنِ أُمِّهِ وَأَنَّ السَّعِيدَ مَنْ وُعِظَ لِغَيْرِهِ فَقَالَ مِنْ أَيِّ ذَلِكَ عَجِبْتَ؟ قُلْتُ أَيَشْقَى أَحَدٌ بِغَيْرِ عَمَلٍ؟ فَأَهْوَى بِيَدَيِهِ إِلَى أُذُنَيْهِ وَقَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ بِأُذُنَيَّ هَاتَيْنِ وَهُوَ يَقُولُ تَقَعُ النُّطْفَةُ فِي الرَّحِمِ أَرْبَعِينَ لَيْلَةً ثُمَّ يَتَصَوَّرُ عَلَيْهَا الْمَلَكُ حَسِبْتُهُ قَالَ الَّذِي يَخْلُقَهَا فَيَقُولُ يَا رَبِّ أَذَكَرٌ أَمْ أُنْثَى؟ فَيَجْعَلُهَا ذَكَرًا أَوْ أُنْثَى فَيَقُولُ يَا رَبِّ أَسَوِيٌّ أَمْ غَيْرُ سَوِيٍّ؟ فَيَجْعَلُهُ اللهُ ﷻ سَوِيًّا أَوْ غَيْرَ سَوِيٍّ فَيَقُولُ يَا رَبِّ مَا أَجَلُهُ؟ مَا خَلْقُهُ؟ فَيَقُولُ يَا رَبِّ أَشَقِيٌّ أَمْ سَعِيدٌ؟ فَيَجْعَلُهُ اللهُ تَعَالَى شَقِيًّا أَوْ سَعِيدًا

"إِنَّ النطفةَ تقعُ في الرحمِ أَربعين ليلةً، ثم يتَصَوَّرُ ، عليها الملَكُ الذى يُخَلِّقُهَا، فيقولُ: ياربِّ، أذَكَرٌ أو أُنثى؟ فيجعَلُه اللَّه ذكرًا أو أُنثَى، ثم يقولُ: ياربِّ أسَوِىٌّ أو غيرُ سَوِىٍّ؟ فيجعَلُه اللَّه سَوِيًّا أوْ غيرَ سوىٍّ، ثم يقول: يارَبِّ ما رزقُه؟ ما أجلُه؟ ما خُلُقُهُ؟ ثم يَجْعلُه اللَّهُ شَقِيًا أوْ سَعِيدًا".
