Ayesha said, "My uncle through breastfeeding came seeking permission to enter, and I refused to admit him until I could ask the Messenger of Allah ﷺ about it. When the Messenger of Allah ﷺ arrived, I asked him about the matter."He said, "He is your uncle, so let him in."She said, "I replied, 'Messenger of Allah, it was the woman who nursed me, not the man.'"He said, "He is indeed your uncle, so let him come in to you."Ayesha added, "This was after the veil had been imposed upon us."Ayesha also said, "What is forbidden through breastfeeding is the same as what is forbidden through birth."
جاء عمي من الرضاعة يستأذن علي، فأبيت أن آذن له علي، حتى أسأل رسول الله ﷺ عن رسول ذلك. فجاء رسول الله ﷺ فسألته عن ذلك. فقال: إنه عمك فأذني له قالت: فقلت: يا رسول الله، إنما أرضعتني المرأة ولم يرضعني الرجل. فقال: إنه عمك فليلج عليك. قالت عائشة: وذلك بعد ما ضرب علينا الحجاب. وقالت عائشة: يحرم من الرضاعة ما يحرم من الولادة.
