I brought Ibn Zubayr to the Prophet ﷺ, and he softened a date and rubbed it on the baby's palate, then said, "This is Abdullah, and you are Umm Abdullah."
حدثنا عبد الله بن محمد قال عبد الله وسمعته أنا من عبد الله بن محمد قال حدثنا حفص عن هشام بن عروة عن عباد بن حمزة بن عبد الله بن الزبير
أتيت النبي ﷺ بابن الزبير فحنكه بتمرة وقال هذا عبد الله وأنت أم عبد الله
Its isnad is sahih. Bukhari narrated it, 7/248, no. 3910, and Tirmidhi, 5/680, no. 3826, and he said, hasan gharib, both in the Book of Merits, and Muslim, 3/1691, no. 2148, in the Book of Manners.
