bayhaqi:7292al-Ḥakam > Ṭāwus > Ibn ʿAbbās

[Machine] When the Messenger of Allah ﷺ sent Mu'adh to Yemen, he was asked: "What have you been commanded?" He replied: "I have been commanded to take from the livestock thirty young she-camels or she-goats, and from every forty, one aged animal." Abu Abdullah Al-Hafiz informed us, who heard from Abu Amr Uthman bin Ahmad Ad-Daqqaq, who heard from Muhammad bin Ubaydullah Al-Munadi, who heard from Abu Badr Shuja' ibn Al-Walid, who heard from Al-Hasan bin Ammarah, who heard from Al-Hakam, who mentioned it and had a witness with a stronger chain than his.
