Advising Family Members and Changing Wrongdoing in the Home Without Authority

Question:
Honorable Shaykh Salih, peace be upon you and Allah’s mercy and blessings. How can I advise my family at home and change the wrongdoings there, when I have no authority in the house? Am I sinful for sitting with my family while there is wrongdoing in the house?

Answer:
In any case, Allah the Exalted said: So you must do what you are able to. If you have authority in the house, change it by hand. If you do not have authority in the house, and the one who is older than you and in charge of the household affairs is older than you, then you must offer advice. Do not, do not grow weary of advice or despair of guidance. You must offer advice and remain in the house. Do not isolate yourself. Remain in the house and always and forever offer advice.
Do not despair. Also use wisdom, gentleness, and softness with them, so that perhaps they will be guided. Perhaps they will, because they are Muslims, but they have some deviations. They are Muslims, but they have some deviations that need treatment and need guidance. So you continue with them, may Allah reward you with good, in guiding and directing them. Yes.
