Hazrat Uqbah bin Amir (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings of Allah be upon him) said, "Avoid going to women." Upon this, a companion from the Ansar tribe asked, "O Messenger of Allah! What is your opinion about the brother-in-law? (Can he go to his brother's wife or not?)" The Messenger of Allah (peace and blessings of Allah be upon him) replied, "The brother-in-law (or elder brother-in-law) going there is (like) destruction."
