Sayyidah Fatimah al-Kubra (may Allah be pleased with her) says: The Prophet (peace and blessings be upon him) said: "The children of every woman have 'asabah (agnatic relatives) to whom they are attributed, except for the children of Fatimah; I am their guardian and I am their 'asabah."
Al-Tabarani recorded it; its chain contains a narrator, Shaybah bin Na'amah, and he is da'if (weak).
