Sahih Muslim Book - 17, Hadith - 3575

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِى شَيْبَةَ وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا ابْنُ نُمَيْرٍ عَنْ هِشَامٍ عَنْ أَبِيهِ عَنْ عَائِشَةَ قَالَتْ جَاءَ عَمِّى مِنَ الرَّضَاعَةِ يَسْتَأْذِنُ عَلَىَّ فَأَبَيْتُ أَنْ آذَنَ لَهُ حَتَّى أَسْتَأْمِرَ رَسُولَ اللَّهِ -صلى الله عليه وسلم- فَلَمَّا جَاءَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- قُلْتُ إِنَّ عَمِّى مِنَ الرَّضَاعَةِ اسْتَأْذَنَ عَلَىَّ فَأَبَيْتُ أَنْ آذَنَ لَهُ. فَقَالَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- « فَلْيَلِجْ عَلَيْكِ عَمُّكِ ». قُلْتُ إِنَّمَا أَرْضَعَتْنِى الْمَرْأَةُ وَلَمْ يُرْضِعْنِى الرَّجُلُ قَالَ « إِنَّهُ عَمُّكِ فَلْيَلِجْ عَلَيْكِ ».

It was narrated that 'Aishah said: "My paternal uncle through breastfeeding came and asked permission to enter upon me, and I refused to give him permission until I consulted the Messenger of Allah (s.a.w). When the Messenger of Allah (s.a.w) came, I said: 'My paternal uncle through breastfeeding came and asked for permission to enter upon me, but I refused to give him permission.' The Messenger of Allah (s.a.w) said: 'Let your uncle enter upon you.' I said: 'But it is the woman who breastfed me; the man did not breastfeed me.' He said: 'He is your uncle, let him enter upon you.'"
