Hadith.5595 - Muhammad ibn Abi Umayr narrated from Al-Husayn ibn Nu'aym from Abu Al-Hasan Imam Musa ibn Jafar Al-Kadhim عليه السلام who said: I asked Imam عليه السلام about a man who granted residence in his house to another man for the duration of his life or made it for him and his descendants after him. Imam عليه السلام said: "It belongs to him and his descendants as stipulated." I asked: "If he needs to sell it, can he sell it?" Imam عليه السلام replied: "Yes." I asked: "Does selling the house invalidate the right of residence?" Imam عليه السلام said: "No, the sale does not invalidate the right of residence. I heard my father عليه السلام say that Abu Jafar Imam Muhammad ibn Ali Al-Baqir عليه السلام said: 'The sale does not invalidate the lease nor the residence, but he sells it on the condition that the buyer does not own what he has purchased until the term of residence or lease ends according to the stipulated condition.'" I asked: "If the seller returns the money to the tenant and covers all expenses he incurred for maintenance and living during the lease, does that end the agreement?" Imam عليه السلام said: "If it is done willingly and with the tenant's consent, then there is no harm in it."
