Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Harith (may Allah be pleased with him) that a person refused to take an oath before Hazrat Shurayh (may Allah have mercy on him). Hazrat Shurayh (may Allah have mercy on him) gave his verdict. That person then said, "I will take the oath." Hazrat Shurayh (may Allah have mercy on him) said, "My decision has now been made."

Hazrat Ibn Abbas (may Allah be pleased with both of them) asked a woman to take an oath; she refused to take the oath, so he made the oath binding upon her. (That is, without the oath, her case would not be decided.)

Hazrat Ibn Umar (may Allah be pleased with both of them) sold a slave for eight hundred dirhams. The buyer found a defect in him and brought the dispute to Hazrat Uthman (may Allah be pleased with him). Hazrat Uthman (may Allah be pleased with him) inquired: Did you sell him free of defects? He refused to take an oath, so Hazrat Uthman (may Allah be pleased with him) returned the slave to them.

It is narrated from Hazrat Mughira and Hazrat Shabirma that Hazrat Abdullah bought a slave. When he brought him home, the slave developed a fever. He took the slave back to return him, and the dispute was brought before Hazrat Shabi (may Allah have mercy on him). He (may Allah have mercy on him) said to Hazrat Abdullah: Present witnesses that he concealed the defect of the slave from you. He (may Allah have mercy on him) said: I have no witnesses. Hazrat Shabi (may Allah have mercy on him) said to the other person: Swear an oath that you did not sell the slave while he was ill. That person said: I defer the oath to Abdullah. Hazrat Shabi (may Allah have mercy on him) decided that Abdullah should take the oath and said: You must swear an oath, otherwise the slave will be binding upon you.
