“I once asked abu ‘Abd Allah (a.s.), about a house which is not yet distributed and a certain one of the people of the house gives his share as charity. He (the Imam) said, ‘It is permissible.’ I then asked, ‘What happens if it is a grant?’ He (the Imam) said, ‘It is permissible.’ I then asked him (the Imam) about a man who allows another man to use his house for his lifetime. He (the Imam) said, ‘It is permissible but he cannot evict him.’ I then asked, ‘Can it be for him and those whom he leaves behind?’ He (the Imam) said, ‘It is permissible.’ I then asked about the case in which one gives permission to another person to use a house without the mention of time duration. He (the Imam) said, ‘He can ask him to leave if he wants him to vacate the house.’”
