Sunan Ibn Majah, Book 9, Hadith 2012 (In-Book) ⓘ
It was narrated from 'Aishah: that the Messenger of Allah said: 'Breast-feeding makes unlawful (for marriages) the same things that blood tie make unlawful.”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، عَنِ الْحَجَّاجِ، عَنِ الْحَكَمِ، عَنْ عِرَاكِ بْنِ مَالِكٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " يَحْرُمُ مِنَ الرَّضَاعِ مَا يَحْرُمُ مِنَ النَّسَبِ " .
