Sexual etiquette in marriage within Islam
At the beginning of sexual intercourse, pronounce the name of God by reciting "Bismillah" and recite the Takbir and Tahlil after Chapter Ikhlas and say 'O God, if Thou takest out semen from my back, make it a good issue.' The Prophet said: 'In the name of Allah. O Allah! Protect us from Satan and also protect what you bestow upon us (i.e. the coming offspring) from Satan, and if it is destined that they should have a child then, Satan will never be able to harm that offspring." The result is that the devil will not be able to injure a child that is born from this intercourse.
Don't face the Ka'bah at the time of intercourse and cover your body and the body of your wife. The Prophet used to cover his head, close his mouth and say to his wife, 'Take peace.' There is a Hadith which says: When anyone of you comes to his wife, let him not fall suddenly upon her, but let him speak words of love to her and then kiss each other. The Prophet said: Let none of you fall suddenly upon his wife like a lower animal. Let him send the Envoy before cohabitation. Someone asked 'What is the Envoy O Prophet?' He said, 'kisses and words of love.' The Prophet said: In three matters, the weakness of a male is disclosed. Firstly if a lover meets his beloved, and then they separate without enquiring into their mutual condition and health; secondly, rejecting the honour which someone wishes to pay him [i.e., by rejecting a gift which was offered]; thirdly to engage in sexual intercourse with the wife or the female who is legally permitted, without talking to her or kissing her or by being unable to restrain the ejaculation of semen before that of his wife.
It is not commendable to cohabit with the wife on the first, middle and last days of the lunar month. It is commendable to cohabit on a Friday evening. After ejaculation, the husband should let his body lay some time upon his wife until she climaxes, as she is slower to climax. It is painful for her to be separated from her husband once her sexual passion has been aroused.
A young husband should enjoy sexual intercourse with his wife once every four days. To preserve the character of the wife, this may be increased or decreased. Sexual intercourse with the wife at the time of her menstruation is unlawful. However, it is lawful to enjoy her without sexual intercourse e.g. enjoy the region beneath the petticoat, or if there be such a need, even use the wife's hand for his ejaculation and stop short of actual copulation [in Arabic terminology, this is known as jima' bil yad, which means 'intercourse by hand.'] God says: "Your wives are a tilth unto you; so go to your tilth when and how you will." A man may keep company with his wife during her menstrual period for eating, resting/sleeping [without copulation] or other purposes. He is not obliged to avoid her.
