With this chain of transmission, from Muhammad ibn Ya'qub, from Ali ibn Ibrahim, from his father, from Ibn Abi Umayr, from Mu'awiyah ibn Ammar, from Muyassir. He said: I said to Abu Abdullah عليه السلام: "I instruct the servant girl to wash my garment from semen, but she does not wash it thoroughly. Then I pray in it, and afterward, I find it dry." Imam عليه السلام said: "Repeat your prayer. However, if you had washed it yourself, there would have been nothing required of you."
