What do the Ulamas say about this matter? Can a person go for Umrah with his wife, mother in law and the sister in law (wife's sister)? Please reply in the light of Qur'an and Hadees. Thanks.
It is permissible for a person to go on Haj and Umrah with his wife and the mother in law but if the sister in law is an adult and there is no other Mahrem (a male whose marriage is unlawful to her) to accompany, it is not permissible for her to travel with her brother in law and it is necessary to abstain from it.
