Musnad Ahmad 30:1283

Muhammad ibn Bishr narrated to us, Mis'ar narrated to us, 'Abd al-Malik ibn 'Umayr narrated to me, from Musa ibn Talhah, from Abu Hurayrah, who said: When the verse was revealed: "And warn your closest kindred" [Ash-Shu'ara: 214], he began to call the clans of Quraysh, one by one: "O children of so-and-so, save yourselves from the Fire." Until he reached Fatimah, and he said: "O Fatimah, daughter of Muhammad, save yourself from the Fire, for I possess no power to benefit you against Allah in anything, except that you have a kinship which I will moisten with its moisture."
