Musnad Ahmad

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Khalid—meaning al-Hadhdha’—from Abu Bishr al-Anbari, from Ibn al-Thalib, from his father, from the Prophet ﷺ: "A man emancipated his share of a slave, and the Prophet ﷺ did not make him liable." Thus said Ghundar: Ibn al-Thalib, but it is actually Ibn al-Talib, and Shu'bah had something in his speech—meaning a lisp—and perhaps Ghundar did not understand him.
