Those who disliked giving a slave a manumission contract if he has no trade

Sayyiduna Umar (may Allah be pleased with him) wrote to Sayyiduna Umayr bin Sa'd (may Allah be pleased with him): "To proceed: Forbid the Muslims near you from making their slaves mukatab (contracted to buy their freedom) on the basis of begging from people."

Sayyiduna Ibn Umar (may Allah be pleased with them both) disliked that a slave should be made mukatab when he has no profession.

Sayyiduna Ibn Umar (may Allah be pleased with them both) made his slave mukatab, and the slave came to him with an instalment of his freedom payment when it fell due. He asked: "Where did you get this from?" The slave said: "I begged from people and did some work." Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "Do you want to feed me the filth of people's wealth? Go, you are free, and take your instalment with you."

Sayyiduna Salman (may Allah be pleased with him) intended to make his slave mukatab, and asked him: "Where will you bring the money from?" He said: "By begging from people." He said: "Do you want to feed me the filth of people?" Then he refused to make him mukatab.

Amir (may Allah have mercy on him) said: "If you wish, make him mukatab, and if you wish, do not."

Sayyiduna Ibn Abbas (may Allah be pleased with them both) made his slave mukatab and stipulated that he would not beg from people.
