"Aishah said: 'The Messenger of Allah entered upon me and there was a man sitting with me. He got upset about that, and I saw the anger in his face.' I said: "O Messenger of Allah, he is my brother through breast-feeding." He said: "Be careful who you count as your brothers" --or: "be careful who you count as your brothers through breast-feeding"-- "for the breast-feeding (which makes marriage prohibited) is from hunger." (Using translation from Nasāʾī 3312)  

عَائِشَةُ دَخَلَ عَلَيَّ رَسُولُ اللهِ ﷺ وَعِنْدِي رَجُلٌ قَاعِدٌ فَاشْتَدَّ ذَلِكَ عَلَيْهِ وَرَأَيْتُ الْغَضَبَ فِي وَجْهِهِ فَقُلْتُ يَا رَسُولَ اللهِ إِنَّهُ أَخِي مِنَ الرَّضَاعَةِ فَقَالَ رَسُولُ اللهِ ﷺ انْظُرْنَ إِخْوَتَكُنَّ وَقَالَ مَرَّةً أُخْرَى انْظُرْنَ مَنْ إِخْوَتَكُنَّ مَنْ الرَّضَاعَةِ فَإِنَّمَا الرَّضَاعَةُ مِنَ الْمَجَاعَةِ  

“No prohibition results from suckling except for what penetrates the intestines while on the breast before weaning.” (Using translation from Tirmidhī 1152)  

قَالَ رَسُولُ اللهِ ﷺ «لَا يُحَرِّمُ مِنَ الرَّضَاعِ إِلَّا مَا فَتَقَ الْأَمْعَاءَ فِي الثَّدْيِ وَكَانَ قَبْلَ الْفِطَامِ»  

“No prohibition results from suckling except for what penetrates the intestines while on the breast before weaning.” (Using translation from Tirmidhī 1152)   

«لَا يُحَرِّمُ مِنَ الرَّضَاعَةِ إِلَّا مَا فَتَقَ الْأَمْعَاءَ»  

[Machine] The Messenger of Allah ﷺ said, "The act of suckling does not make prohibited what is forbidden by genealogy. It is only forbidden what is prohibited by the presence of milk (in the breast)."  

قَالَ رَسُولُ اللهِ ﷺ «لَا يُحَرِّمُ مِنَ الرَّضَاعَةِ الْمَصَّةُ وَلَا الْمَصَّتَانِ إِنَّمَا يُحَرِّمُ مَا فَتَقَ اللَّبَنُ»
