“I once asked abu ‘Abd Allah (a.s.), about the case of a man who allows another man to use a house and those whom he will leave behind. He (the Imam) said, ‘It is permissible but they cannot sell or inherit it.’ I asked if a man could allow another man to use a house for his lifetime. He (the Imam) said, ‘It is permissible.’ I then asked what happens if a man allows another man to use a house without the mention of time. He (the Imam) said, ‘It is permissible but he can ask him to vacate if he wants.’”
