وَ رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ هِشَامِ بْنِ سَالِمٍ عَنْ بُرَيْدٍ اَلْعِجْلِيِّ قَالَ: قُلْتُ لِأَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ أَ رَأَيْتَ قَوْلَ رَسُولِ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ "يَحْرُمُ مِنَ اَلرَّضَاعِ مَا يَحْرُمُ مِنَ اَلنَّسَبِ" فَسِّرْهُ لِي فَقَالَ "كُلُّ اِمْرَأَةٍ أَرْضَعَتْ مِنْ لَبَنِ فَحْلِهَا وَلَدَ اِمْرَأَةٍ أُخْرَى مِنْ جَارِيَةٍ أَوْ غُلاَمٍ فَذَلِكَ اَلرَّضَاعُ اَلَّذِي قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ وَ كُلُّ اِمْرَأَةٍ أَرْضَعَتْ مِنْ لَبَنِ فَحْلَيْنِ كَانَا لَهَا وَاحِداً بَعْدَ آخَرَ مِنْ جَارِيَةٍ أَوْ غُلاَمٍ فَإِنَّ ذَلِكَ رَضَاعٌ لَيْسَ بِالرَّضَاعِ اَلَّذِي قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ "يَحْرُمُ مِنَ اَلرَّضَاعِ مَا يَحْرُمُ مِنَ اَلنَّسَبِ"".
Al-Hasan ibn Mahbub narrated from Hisham ibn Salim from Burayd al-Ijli who said: I asked Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام: "What is the meaning of the saying of the Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family) - 'What is unlawful through lineage is also unlawful through breastfeeding'? Explain it to me." Imam عليه السلام replied: "Every woman who nurses, with the milk of her husband, the child of another woman, whether the child is male or female, that is the breastfeeding (ridha') referred to by the Messenger of Allah سبحانه وتعالى (may Allah bless him and his family). But any woman who nurses, with the milk of two different husbands (one after the other), the child of another woman, whether male or female, this is breastfeeding that does not fall under the ruling of the statement of the Messenger of Allah سبحانه وتعالى 'What is prohibited through breastfeeding is the same as what is prohibited through lineage.'"
