وَعَنْهَا: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَخَلَ عَلَيْهَا وَعِنْدَهَا رَجُلٌ فَكَأَنَّهُ كَرِهَ ذَلِكَ فَقَالَت: إِنَّه أخي فَقَالَ: «انظرن من إخوانكن؟ فَإِنَّمَا الرضَاعَة من المجاعة»
She said that the Prophet (sallallahu alayhi wa sallam) visited her when a man was with her and he seemed to disapprove of that. She told him that he was her brother and he replied, “Consider* who your brothers are, for fosterage is that consequent on hunger” (Fosterage applies only to infants and not to children who are able to take solid food). * The verb is in the plural, indicating that this is a general instruction and not simply a reply to Aishah.
