A Muslim's responsibility towards their sinful brothers and sisters

Q 8: What is the extent of a brother's responsibility towards his brother, sister, or either parent if any of them commits a sin and he tries to advise and dissuade them from it?

A: The Muslim should offer his sisters and brothers advice with patience and wisdom. He should instruct them (Part No. 25; Page No. 366) for the Sake of Allah, supporting his advice with evidence from the Qur'an and Sunnah and point out to them the rulings of religious scholars. He should not give up and continue advising them whenever possible. He should repeat it and remind them of the punishments of sinning, following the example of the Messenger of Allah (peace be upon him) and his Companions (may Allah be pleased with them). Hopefully, Allah will guide them!May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
