Hadith 25:116
Ibn Abi ‘Adi narrated to us, from Ash’ath, from al-Hasan, who said: The *mukātab* (a slave under a contract of manumission) may not emancipate [others] nor may he give gifts, except with the permission of his master.
حدثنا بن أبي عدي عن أشعث عن الحسن قال المكاتب لا يعتق ولا يهب إلا بإذن مولاه
