Mut’ah or temporary marriage refers to when a man marries a woman for a specific length of time in return for a particular amount of money. Mut’ah marriage was permitted at the beginning of Islam, then it was abrogated and became haram until the Day of Judgement.

Engagement in Islam means that a man asks to marry a woman and is accepted. The view of the scholars is that engagement is prescribed for one who wants to get married. Prophet Muhammad encouraged the one who wants to get engaged to look at the woman to whom he wishes to propose. What some Muslims do, announcing the engagement, having a party to celebrate and exchanging gifts, all comes under the heading of customs which are permissible in principle.

It is not permissible for a man to be married to two sisters at the same time, or to a woman and her paternal or maternal aunt at the same time.

Whomever Allah blesses with a righteous wife, He has helped him with half of his religion, so let him fear Allah with regard to the other half.
