Hadith.5595 - Muhammad ibn Abi Umayr narrated from Al-Husayn ibn Nu'aym from Abu Al-Hasan Imam Musa ibn Jafar Al-Kadhim who said: I asked Imam 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 said: "It belongs to him and his descendants as stipulated." I asked: "If he needs to sell it, can he sell it?" Imam replied: "Yes." I asked: "Does selling the house invalidate the right of residence?" Imam said: "No, the sale does not invalidate the right of residence. I heard my father say that Abu Jafar Imam Muhammad ibn Ali Al-Baqir 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 said: "If it is done willingly and with the tenant's consent, then there is no harm in it."
