by Shaykh Abdul Aziz Bin Baz (1420AH)
Plural marriage contains general and abundant benefits. However, some people are cowardly regarding this, either due to having a scanty amount of wealth or out of fear of his first wife, her tongue lashing, and her evil, or due to other reasons. Hence, if one has the ability to do it and it is easy for him, then in order that one may be good to the Muslims and safeguard the chastity of the many young ladies, this is better. If it is not easy upon him, then there is no harm upon him ( having only one wife).
