[Machine] He has forbidden you seven forbiddances regarding lineage and seven regarding marriage. Forbidden to you are your mothers, daughters, until the end of the verse.  

حَرَّمَ عَلَيْكُمْ سَبْعًا نَسَبًا وَسَبْعًا صِهْرًا حُرِّمَتْ عَلَيْكُمْ أُمَّهَاتُكُمْ وَبَنَاتُكُمْ إِلَى آخِرِ الْآيَةِ  

[Machine] Ibn Abbas said, "Seven (marriages) through marriage and seven through lineage, and what is prohibited by lineage is also prohibited by breastfeeding."  

قَالَ ابْنُ عَبَّاسٍ سَبْعٌ صِهْرٌ وَسَبْعٌ نَسَبٌ وَيَحْرُمُ مِنَ الرَّضَاعِ مَا يَحْرُمُ مِنَ النَّسَبِ  

The Prophet ﷺ said: What is unlawful by reason of consanguinity is unlawful by reason of fosterage. (Using translation from Abū Dāʾūd 2055)   

رَسُولَ اللهِ ﷺ قَالَ يَحْرُمُ مِنَ الرَّضَاعَةِ مَا يَحْرُمُ مِنَ الْوِلَادَةِ  

[Machine] Aisha, the wife of the Prophet ﷺ , informed him that the Messenger of Allah ﷺ was with her and that she heard the sound of a man seeking permission to enter Hafsa's house. Aisha said to him, "O Messenger of Allah, a man seeking permission to enter your house." The Messenger of Allah ﷺ said, "I think it is so-and-so, who is brother in nursing to Hafsa." Aisha said, "O Messenger of Allah, if he were alive, would he have entered upon me?" The Messenger of Allah ﷺ said, "Yes, for breastfeeding prohibits what birth prohibits."  

أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ أَخْبَرَتْهَا أَنَّ رَسُولَ اللهِ ﷺ كَانَ عِنْدَهَا وَأَنَّهَا سَمِعَتْ صَوْتَ رَجُلٍ يَسْتَأْذِنُ فِي بَيْتِ حَفْصَةَ قَالَتْ عَائِشَةُ فَقُلْتُ يَا رَسُولَ اللهِ رَجُلٌ يَسْتَأْذِنُ فِي بَيْتِكَ قَالَتْ فَقَالَ رَسُولُ اللهِ ﷺ أَرَاهُ فُلَانًا لِعَمِّ حَفْصَةَ مِنَ الرَّضَاعَةِ فَقَالَتْ عَائِشَةُ يَا رَسُولَ اللهِ لَوْ كَانَ فُلَانٌ حَيًّا لِعَمِّهَا مِنَ الرَّضَاعَةِ دَخَلَ عَلَيَّ؟ فَقَالَ رَسُولُ اللهِ ﷺ نَعَمْ إِنَّ الرَّضَاعَةَ تُحَرِّمُ مَا تُحَرِّمُ الْوِلَادَةُ
