Hazrat Sha'bi states that if a free person admits to being a slave over himself, he will not become a slave.

It is narrated from Hazrat Harith that a person said, "I was the slave of such-and-such person, or my father was the slave of such-and-such person, or my mother was the bondwoman of such-and-such person." That person said, "Today you are my slave." The Prophet said that if they were already free and it is known that they are slaves, then they will not be considered slaves merely by someone’s claim, unless he brings just witnesses. And those witnesses testify that this person is a slave.

Hazrat Hakam states that if a debt is incurred by one of the partners, it will be obligatory upon both of them.

Hazrat Shurayh (may Allah have mercy on him) said that the guarantor will be liable.

Muhammad, may Allah have mercy on him, says: I submitted to Hazrat Shurayh: My guarantor acted with trickery apart from me, and a judgment was made regarding my wealth, and the wealth of my debtor was distributed apart from me. He said: If the guarantor had the choice, then he is liable, and you have more right to your wealth, and if your debtor's wealth was distributed apart from you, then it will be according to the shares.

Hazrat Abu Umamah al-Bahili (may Allah be pleased with him) narrates that I heard the Noble Prophet (peace and blessings be upon him) saying during the Farewell Pilgrimage sermon that it is necessary in all circumstances to repay a debt, and the guarantor is responsible (for the repayment of the debt).

Hazrat Tawus and Hazrat Mujahid state that by Allah's command { فَکَاتِبُوہُمْ إِنْ عَلِمْتُمْ فِیہِمْ خَیْرًا }, what is meant is wealth and trust.

Hazrat Ata says that it means his wealth.

Hazrat Ubaidah says that when he offers prayer.

Hazrat Ata says that it means his wealth.
