Is it permissible for him to live with his uncle when the uncle has adult daughters?

We advise against living with the uncle and his family due to the questioner not being a mahram to his uncle's wife and daughters. This is based on the Prophet's (peace be upon him) prohibition against entering upon women and his likening of the hamw (male in-law, like a brother-in-law or uncle's husband) to death. If living there is necessary or temporary, then it is obligatory to ensure there is no khalwa (private seclusion) with them, to lower the gaze, to avoid soft speech, and for the uncle's wife and daughters to adhere to the legal hijab.
