Musannaf Ibn Abi Shaybah

Hazrat Ibn Jurayj states that Hazrat Umar bin Abdul Aziz had written a letter, which I read: When goods are found with a suspect and he says, "I bought them, but I have not used them," he should be put in prison, and no one's statement in his favor should be accepted until Allah reveals the truth. I mentioned this matter to Hazrat Ata, and he found it strange.
