Musannaf Ibn Abi Shaybah 28414 — A man who shackles his slave

Sa'd bin Yusuf bin Ya'qub said that some people spoke to Tawus about a slave of his, and he said: "He has no wealth, that I might grant him a contract of manumission (kitabah), nor is he righteous, that I might marry him off." He disliked beating, and he would say: "Fetters."
