Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates: I heard the Messenger of Allah (peace and blessings be upon him) say:“Listen! No man should sit in seclusion with a woman except that there is a mahram relative with her, and no woman should travel except that there is a mahram relative with her.”A man said: O Messenger of Allah! My name has been written for such-and-such battle, while my wife is going for Hajj. So the Prophet (peace and blessings be upon him) said:“Go and perform Hajj with your wife.”
