"What becomes unlawful (for marriage) through birth becomes unlawful through breast-feeding."  

عَنِ النَّبِيِّ ﷺ قَالَ مَا حَرَّمَتْهُ الْوِلاَدَةُ حَرَّمَهُ الرَّضَاعُ  

"Do not observe Hijab before him, for what becomes unlawful (for marriage) through breast-feeding is that which becomes unlawful through lineage."  

أَنَّ عَمَّهَا مِنَ الرَّضَاعَةِ يُسَمَّى أَفْلَحَ اسْتَأْذَنَ عَلَيْهَا فَحَجَبَتْهُ فَأُخْبِرَ رَسُولُ اللَّهِ ﷺ فَقَالَ لاَ تَحْتَجِبِي مِنْهُ فَإِنَّهُ يَحْرُمُ مِنَ الرَّضَاعِ مَا يَحْرُمُ مِنَ النَّسَبِ  

"What becomes unlawful (for marriage) through breast-feeding is that which becomes unlawful through lineage."  

عَنِ النَّبِيِّ ﷺ قَالَ يَحْرُمُ مِنَ الرَّضَاعِ مَا يَحْرُمُ مِنَ النَّسَبِ  

"I heard 'Aishah say: The Messenger of Allah said: 'What becomes unlawful (for marriage) through breast-feeding is that which becomes unlawful through birth.'"  

قَالَ رَسُولُ اللَّهِ ﷺ يَحْرُمُ مِنَ الرَّضَاعِ مَا يَحْرُمُ مِنَ الْوِلاَدَةِ
