Please let me know about the concept of Mut`a. Is it allowed in Islam?
Mut'a means marriage up to a predetermined period of time. Some of the Shia sects like the Imāmīyah sect allow it (Fiqh al-Sunnah, Syed Sabiq, Vol, 2 Pg 167). They base their view on the Qur'ānic verse (5:24), which, I am afraid, is erroneously translated.
The Qur’ān explicitly prohibits such a relationship.
According to the Qur’ān one can have a sexual relationship only with a woman who is his wife out of permanent wedlock.
Also, it is known that the institution of slavery existed in the times of the Prophet (sws). Islam chalked out a complete programme for the eradication of this evil from the society. However, since it was deeply rooted in the society, a gradual scheme of its elimination was adopted. During this interim period, when slavery was not completely prohibited, sexual relations with slave girls was allowed as well. The Qur'an says:
And those who guard their chastity except with their wives and slave girls. For they are not to be blamed [in these cases]. But those who exceed beyond this are transgressors." (70:29-31)
