Believers as Offspring of Unbelievers
2 Aḥadīth
Al-Husayn ibn Muhammad has narrated from Mu’ alia ibn Muhammad from al- Hassan ibn Ali al-Washsha’ from Ali ibn Maysara who has said the following:“Abu ‘Abd Allah 
has said, ‘The seed for a believer may exist in the back of a pagan and no evil affects it until it is transferred into the womb of a pagan woman wherein no evil affects it also. It is not affected even after birth and up to the time the person is considered responsible for his/her deeds.’”
الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ عَلِيٍّ الْوَشَّاءِ عَنْ عَلِيِّ بْنِ مَيْسَرَةَ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيهِ السَّلام) إِنَّ نُطْفَةَ الْمُؤْمِنِ لَتَكُونُ فِي صُلْبِ الْمُشْرِكِ فَلا يُصِيبُهُ مِنَ الشَّرِّ شَيْءٌ حَتَّى إِذَا صَارَ فِي رَحِمِ الْمُشْرِكَةِ لَمْ يُصِبْهَا مِنَ الشَّرِّ شَيْءٌ حَتَّى تَضَعَهُ فَإِذَا وَضَعَتْهُ لَمْ يُصِبْهُ مِنَ الشَّرِّ شَيْءٌ حَتَّى يَجْرِيَ عَلَيْهِ الْقَلَمُ.
Hadith No. 2
Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Ali ibn Yaqtin from abu al-Hassan Musa who has said the following: “Once I said to the Imam, ‘I am afraid of the prayer of Abu ‘Abdillah against Yaqtin and his offspring.’ The Imam said, ‘O abu al-Hassan, it is not as you think. A believer in the back of an unbeliever is like a small piece of stone in a brick. Rain can wash away the brick but it never harms the solid piece of stone.’”
عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عَلِيِّ بْنِ يَقْطِينٍ عَنْ أَبِي الْحَسَنِ مُوسَى (عَلَيهِ السَّلام) قَالَ قُلْتُ لَهُ إِنِّي قَدْ أَشْفَقْتُ مِنْ دَعْوَةِ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) عَلَى يَقْطِينٍ وَمَا وَلَدَ فَقَالَ يَا أَبَا الْحَسَنِ لَيْسَ حَيْثُ تَذْهَبُ إِنَّمَا الْمُؤْمِنُ فِي صُلْبِ الْكَافِرِ بِمَنْزِلَةِ الْحَصَاةِ فِي اللَّبِنَةِ يَجِيءُ الْمَطَرُ فَيَغْسِلُ اللَّبِنَةَ وَلا يَضُرُّ الْحَصَاةَ شَيْئاً.
