Marriage Fiqh: A sister cannot be married against wife [as Mehar] (Shighar is not permitted)

In some tribal areas of Indo pak, Afghanistan and Arabia, some times a sister is married with brother of wife without paying mehar this is known as Nikah of Shighar.

This is a very bad tradition and it increases the chances of divorce and domestic voilence. Rasool salal laho aliehi waslam has banned it.

Now a man cannot marry her sister or daughter with his brother in law without mehar. He can however marry her with his brother in law without setting any link of this marriage with his own marriage.
