In Islam, contrary to Christianity, marriage and sex are not antipathetic to the love for and worship of God. Instead of an obstacle, marriage is regarded as an asset in acquiring spiritual perfection.
The Prophet said, "One who marries has already guarded half of his religion, therefore he should fear Allah for the other half." (Wasa'il, Vol. 14, p.5) A person who can fulfill his sexual urges lawfully is less distracted in the spiritual journey. Love for women and faith are inter-related. In one hadith, 'Umar bin Zayd quotes Imam Ja'far as-Sadiq that, "I do not think that a person's faith can increase positively unless his love for women has increased." (Wasa'il, Vol. 14, p.9) The same Imam said, "Whenever a person's love for women increases, his faith increases in quality." (Wasa'il, Vol. 14, p.11) He also said, "Whosoever's love for us increases, his love for women must also increase." (Wasa'il, Vol. 14, p.11)
Marriage even elevates the value of prayers. The Prophet said, "Two rak 'ats (cycles) prayed by a married person is better than the night-vigil and the fast of a single person." (Wasa'il, Vol. 14, p.7) Ibn Fuzzal quotes Imam Ja'far as-Sadiq saying that, "Two rak'ats prayed by a married person is better than seventy rak'ats prayed by a single person." (Wasa'il, Vol. 14, p.6)
The Prophet said, "If anyone likes to meet Allah in purity, then he should meet Him with a wife." (Wasa'il, Vol. 14, p. 25)
A woman came to the Prophet's house and her strong perfume soon filled the house. When the Prophet inquired about the visitor, the woman said that she had tried everything to attract her husband but in vain; he does not leave his meditation to pay any attention to her.
The Prophet told her to inform her husband about the reward of sexual intercourse which he described as follows: "When a man approaches his wife, he is guarded by two angels and [at that moment in Allah's views] he is like a warrior fighting for the cause of Allah. When he has intercourse with her, his sins fell like the leaves of the tree [in fall season]. When he performs the major ablution, he is cleansed from sins. (Wasa'il 'sh-Shi'ah, Vol. 14, p. 74)
