Ali ibn Talib reported that when the illness of the Prophet (ﷺ) deepened, he said, "'Ali! Bring me a page on which I can write something for my community after which they will not go astray." 'Ali said, "I feared that he would die before I could do that, so I said, 'I will remember better than the paper.' His head was between my forearm and my leg. He recommended the prayer, zakat and kind treatment of slaves. he spoke like that until he died." He commanded him to testify, "There is no god but Allah and Muhammad is His slave and Messenger. Anyone who testifies to that is saved from the Fire."

Abdullah reported that the Prophet (ﷺ) said, "Respond to invitations. Do not reject gifts. Do not beat Muslims."

"The prayer! The prayer! Fear Allah concerning your slaves!"

Abu 'd-Darda' used to say to people. "We know you better than the veterinarian knows his animals. We recognise the best of you from the worst of you. The best of you is the one whose good is hoped for and the one whose evil you are safe from. As for the worst of you, that is the person whose good is not hoped for and whose evil you are not safe from and he does not free slaves."

Abu Umama said, "Ingratitude is typified by someone who refuses to give, lives alone, and beats his slave."

Al-Hasan reported that a man ordered one of his slaves to draw water using one of his camels and the man fell asleep. The master came with a torch and put it in his face and the slave fell into the well. In the morning, the slave went to 'Umar ibn al-Khattab and 'Umar saw what had happened to his slave and therefore 'Umar set him free."

Amra reported that 'A'isha had made one of her slavegirls a mudabbar (one who would be set free after her death). Then 'A'isha became ill and her nephews consulted a gypsy doctor. He said, "You are asking me for information about a bewitched woman. A slavegirl of hers has bewitched her." 'A'isha was told and asked the girl, "Have you put a spell on me?" "Yes," she replied. "Why?' she asked. "Because you will never free me," she answered. Then 'A'isha said, "Sell her to the worst masters among the Arabs."
