The Messenger of Allah ﷺ said, "There is no child born except upon this religion." Waki on one occasion said, "Upon the religion."
حدثنا أبو معاوية ووكيع ومحمد بن عبيد قالوا حدثنا الأعمش وابن نمير حدثنا الأعمش عن أبي صالح
قال رسول الله ﷺ ليس مولود يولد إلا على هذه الملة وقال وكيع مرة على الملة
Its isnad is sahih. Ahmad narrated it here from four of his teachers, from Amash. It is abridged here, and it will come in full later from two of them, from Abu Muawiya from Amash at 7438, and from Waki from Amash at 10246. Muslim also narrated it, 2:302, in full, through the route of Abu Muawiya and Ibn Numayr, both of them from Amash. Something similar in meaning has already passed at 7181, from the narration of Zuhri, from Saeed bin Musayab, from Abu Hurairah. We pointed there to this isnad and the two isnads after it. We also noted that we mentioned many of its routes in detail in the takhrij of hadith 128 of Sahih Ibn Hibban. We have also thoroughly examined its isnads found in the Musnad, in the takhrij of the hadith of Ibn Hibban.
