Muta:
Shi'i reasons for considering mut'a permissible are as follows:
1-The consensus of the Shi'i community.
2-The words of the Qur'an: 'Marry such women as seem good to you!' (4:3), since mut'a is a kind of marriage, but one which men desire to perform by expending their property.
3-The words of the Qur'an: 'So those of them whom you enjoy, give to them their appointed wages' (4:24). The word istimta' (enjoy), unless otherwise qualified, signifies 'temporary marriage.'
4-Ibn Mas'ud's version of the Qur'an, which adds the words 'to a specified term ' to the above verse.
5-There is no disagreement over the fact that mut'a was allowed at the beginning of Islam. So those who claim that the verse was abrogated must prove their assertion.
6-The principle from which discussion must begin is that mut'a is permitted. That it should be forbidden must be proven.
7-The words of 'Umar concerning the 'two mut'as'. Here 'Umar tells us that at the time of the Prophet, mut'a was permitted, i.e., that it was a part of the religion of Islam. Proof must be provided that it is no longer so.
