10. Muhammad ibn Yahya has narrated from Muhammad ibn Al-Husayn from Safwan from Ishaq ibn ‘Ammar who has said the following: “One who had heard from abu ‘Abd Allah (a.s.), informed me saying, ‘A man asked the Imam (a.s.), when I was present. A Muslim man needed to sell his house and he went to his brother and said. “I want to sell this house to you because I like it to be with you instead of being with others, with one condition that if within a year I come back with money to pay you, return it back to me.’” He replied, ‘I agree. If you come back with payment within a year I will give it back to you.’ I further said, ‘This house had a certain amount of income. Who then can have the income?’ He (the Imam) replied, ‘Income belongs to the buyer; were it (the house) to burn down it would come from his property.’”

12. Muhammad ibn Yahya has narrated from Muhammad ibn Al-Husayn from Muhammad ibn ‘Abd Allah ibn Hilal from ‘Uqbah ibn abu Khalid who has said the following: “This is concerning my question before abu ‘ Abd Allah (a.s.), about the case of a man who purchases something from a man and makes a binding deal and then leaving the merchandise with him without taking possession saying, Tomorrow, by the will of Allah, I will come back.’ Someone steals the merchandise. Whose property is it considered? He (the Imam) replied It is the property of the seller until the buyer takes possession and it is taken away from the seller’s house. When this happens the buyer is responsible until he returns it back to the seller.’”
