Musnad Abu Ya'la al-Mawsili 1:117

Abu Khaythama narrated to us, Uthman ibn Umar narrated to us, Malik narrated to us, from al-Zuhri, from Uthman ibn Ishaq, from Qabisa ibn Dhu'ayb, who said: The grandmother came to Abu Bakr asking him about her inheritance. He said: "There is nothing for you in the Book of Allah, and there is nothing for you in the Sunnah of the Messenger of Allah, peace and blessings of Allah be upon him. So return until I ask the people."
