Hadith.5589 - Hammad ibn Uthman narrated from Abu Al-Sabbah Al-Kinani who said: I said to Abu Al-Hasan عليه السلام: "My mother gave me her share in a house as charity. I told her that the judges do not approve of this, but if you write it as a sale, it would be accepted." She replied: "Do whatever you think is appropriate and whatever seems permissible to you." So, I secured it accordingly. Later, one of the heirs wanted me to swear that I had paid the price, even though I had not paid her anything. What do you suggest?" Imam عليه السلام said: "Swear (Oath to Allah سبحانه وتعالى) to him."
