My foster uncle Aflah bin Ubayy Quays came seeking permission to enter upon me after the verse of the veil had been revealed. I refused to grant him permission until the Prophet ﷺ came in to see me. He said, "He is your uncle, so let him in."I said, "It was the woman who nursed me, not the man."He replied, "May your hands be dusty," or he said, "your right hand."
حدثنا أبو بكر بن أبي شيبة حدثنا سفيان بن عيينة عن الزهري عن عروة
أتاني عمي من الرضاعة أفلح بن أبي قعيس يستأذن علي بعد ما ضرب الحجاب فأبيت أن آذن له حتى دخل علي النبي ﷺ فقال إنه عمك فأذني له فقلت إنما أرضعتني المرأة ولم يرضعني الرجل قال تربت يداك أو يمينك
Muslim collected it, in the Book of Suckling (Rada), chapter on the prohibition of suckling from the same man's milk (via a wet nurse who nursed from him), hadith no. 4/1445, from Ibn Abu Shayba with this chain. Bukhari and Muslim both collected it, Bukhari in nos. 3796, 5103, and 6156, and Muslim and others also collected it through other chains from Zuhri, with similar wording, at greater length.
