مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ وَ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ مَحْبُوبٍ عَنِ ابْنِ رِئَابٍ عَنْ زُرَارَةَ بْنِ أَعْيَنَ قَالَ سَمِعْتُ أَبَا جَعْفَرٍ ( عليه السلام ) يَقُولُ إِذَا وَقَعَتِ النُّطْفَةُ فِي الرَّحِمِ اسْتَقَرَّتْ فِيهَا أَرْبَعِينَ يَوْماً وَ تَكُونُ عَلَقَةً أَرْبَعِينَ يَوْماً وَ تَكُونُ مُضْغَةً أَرْبَعِينَ يَوْماً ثُمَّ يَبْعَثُ اللَّهُ مَلَكَيْنِ خَلَّاقَيْنِ فَيُقَالُ لَهُمَا اخْلُقَا كَمَا يُرِيدُ اللَّهُ ذَكَراً أَوْ أُنْثَى صَوِّرَاهُ وَ اكْتُبَا أَجَلَهُ وَ رِزْقَهُ وَ مَنِيَّتَهُ وَ شَقِيّاً أَوْ سَعِيداً وَ اكْتُبَا لِلَّهِ الْمِيثَاقَ الَّذِي أَخَذَهُ عَلَيْهِ فِي الذَّرِّ بَيْنَ عَيْنَيْهِ فَإِذَا دَنَا خُرُوجُهُ مِنْ بَطْنِ أُمِّهِ بَعَثَ اللَّهُ إِلَيْهِ مَلَكاً يُقَالُ لَهُ زَاجِرٌ فَيَزْجُرُهُ فَيَفْزَعُ فَزَعاً فَيَنْسَى الْمِيثَاقَ وَ يَقَعُ إِلَى الْأَرْضِ يَبْكِي مِنْ زَجْرَةِ الْمَلَكِ .
7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad and Ali ibn Ibrahim has narrated from his father from ibn Mahbub from ibn Ri’ab from Zurarah ibn ’ A‘yan who has said the following: “I once heard abu Ja‘far , saying, ‘When the seed falls in the womb it settles there for forty days, remains as a clot for forty days and as an embryo for another forty days. Allah then sends two creative angels with instruction to create him, as Allah wants it to be. It can be a male or a female. They shape him and write down the duration of his life, the time of his death, that he is a fortunate or unfortunate. The two must write down between his eyes the covenant of Allah, which He has taken from him in the condition of being particles. When the time for his coming out from the belly of his mother draws near; Allah sends an angel called admonisher who admonishes him that sends him into shock. He forgets the covenant and falls on the ground weeping because of the admonition of the angel?”
