According to the principles of Islamic jurisprudence...
According to the principles of Islamic jurisprudence, any communication in imperative form from God can have two levels of meaning: either it is an obligatory command or a very high recommendation. And therefore we see that in Islam celibacy is not considered as a virtue. Based on this verse we find the Prophet saying that, "Whoever refrains from marriage because of fear of poverty, he has indeed thought badly of God."[^2] In another verse Allah says: "...
Then marry such women as seem good to you two, three or four. But if you fear that you will not do justice between your wives, then marry only one..." (4:3) Sex has been openly recommended in the Qur'an, "When they [i.e., the wives] have cleansed themselves [after menstruation], you go into them as Allah has commanded." (2:222) The phrase 'commanded you' does not refer to any legislative command; that is, it does not mean that as soon as a person's wife becomes clean from her period, he should immediately have sex with her.
It is a creative command and refers to the sexual urge which Allah has placed in our nature. And when the sexual urge is counted as a creative command of God, then who can associate it in any way with sin and evil?! Marriage and sex are among the signs of God's power and blessings. The Qur'an says, "And among His signs is that He has created for you spouses from among yourselves so that you may live in tranquillity with them; and He has created love and mercy between you.
Verily, in that are signs for those who reflect." (30:21) From these few verses of the Qur'an, one can easily understand that according to Islam: (a) marriage is a sign of God's power and blessings; (b) marriage is a highly recommended act of virtue which should not be avoided because of poverty; (c) sexual urge is a creative command of God placed in human nature. After equating sex with Allah's creative command, there can be no room for equating it with guilt, sin or evil.
* * * The Prophet and the Imams of Ahlu'l Bayt also encouraged their followers to marry and to fulfill their sexual urges in lawful ways as can be seen from the following: The Prophet said, "No house has been built in Islam more beloved in the sight of Allah than through marriage."[^3] The Prophet said, "O you young men! I recommend marriage to you."[^4] Imam 'Ali said, "Marry, because marriage is the tradition of the Prophet.
