Marriage and intimacy
AND DO NOT marry women who ascribe divinity to aught beside God ere they attain to [true] belief: for any believing bondwoman [of God] is certainly better than a woman who ascribes divinity to aught beside God, even though she please you greatly. And do not give your women in marriage to men who ascribe divinity to aught beside God ere they attain to [true] belief: for- any believing bondman [of God] is certainly better than a man who ascribes divinity to aught beside God, even though he please you greatly. [Such as] these invite unto the fire, whereas God invites unto paradise, and unto [the achievement of] forgiveness by His leave; and He makes clear His messages unto mankind, so that they might bear them in mind. (Al Baqarah: 221)
AND THEY will ask thee about [woman's] monthly courses. Say: "It is a vulnerable condition. Keep, therefore, aloof from women during their monthly courses, and do not draw near unto them until they are cleansed; and when they are cleansed, go in unto them as God has bidden you to do." Verily, God loves those who turn unto Him in repentance and He loves those who keep themselves pure. (Al Baqarah: 222)
Your wives are your tilth; go, then, unto your tilth as you may desire, but first provide something for your souls, and remain conscious of God, and know that you are destined to meet Him. And give glad tidings unto those who believe. (Al Baqarah:223) (approach your wives from the front ( vagina) and not the back ( anus). The point of sowing seed and tilth is for offspring's, which means only the front.
The general rule is anything is allowed between man and wife unless clearly and explicitly forbidden.

Sexual relations between a man and wife
Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (peace and blessings of Allah be upon him) said: “The one who has intercourse with his wife in her back passage has disavowed himself of that which was revealed to Muhammad (peace and blessings of Allah be upon him).” Narrated by Abu Dawud (3904); classed as sahih by al-Albani in Sahih Abi Dawud.
Ibn 'Abbas (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings of Allah be upon him) said: “Allah will not look at a man who has intercourse with a woman in her back passage.” Narrated by al-Tirmidhi (1165); classed as sahih by Ibn Daqiq al-‘Eid in al-Ilmam (2/660) and by al-Albani in Sahih al-Tirmidhi.
Khuzaymah ibn Thabit (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings of Allah be upon him) said: “Allah is not too shy to tell the truth” three times. “Do not have intercourse with women in their back passages .” Narrated by Ibn Majah (1924); classed as sahih by al-Albani in Sahih Ibn Majah.
Those who take an oath that they will not approach their wives shall have four months of grace; and if they go back [on their oath] -behold, God is much-forgiving, a dispenser of grace. (Al Baqarah: 226)
And the divorced women shall undergo, without remarrying, a waiting-period of three monthly courses: for it is not lawful for them to conceal what God may have created in their wombs, if they believe in God and the Last Day. And during this period their husbands are fully entitled to take them back, if they desire reconciliation; but, in accordance with justice, the rights of the wives [with regard to their husbands] are equal to the [husbands'] rights with regard to them, although men have precedence over them [in this respect]. And God is almighty, wise. (Al Baqarah:228)
A divorce may be [revoked] twice, whereupon the marriage must either be resumed in fairness or dissolved in a goodly manner. And it is not lawful for you to take back anything of what you have ever given to your wives unless both [partners] have cause to fear that they may not be able to keep within the bounds set by God: hence, if you have cause to fear that the two may not be able to keep within the bounds set by God, there shall be no sin upon either of them for what the wife may give up [to her husband] in order to free herself. These are the bounds set by God; do not, then, transgress them: for they who transgress the bounds set by God-it is they, they who are evildoers! (Al Baqarah:229)
And if he divorces her [finally], she shall thereafter not be lawful unto him unless she first takes another man for husband; then, if the latter divorces her, there shall be no sin upon either of the two if they return to one another-provided that both of them think that they will be able to keep within the bounds set by God: for these are the bounds of God which He makes clear unto people of [innate] knowledge. (Al Baqarah:230)
It is mentioned in the famous Hanafi Fiqh reference book, and one regarded as a fundamental source in the school, al-Fatawa al-Hindiyya: “If a man inserts his penis in his wife’s mouth, it is said that it is disliked( and vice versa) (makruh), and others said that it is not disliked.” (al-Fatawa al-Hindiyya, 5/372)
