Nikkah in the light of Quran & Hadith

[4. Surah An-Nisaa : Ayah 69]
And whoever obeys Allah and the Apostle, these are with those upon whom Allah has bestowed favors from among the prophets and the truthful and the martyrs and the good, and a goodly company are they.

[Sahih Muslim: Volume 8, Book 'Kitab Al-Nikah', Number 3231]
'Alqama reported: While I was walking with 'Abdullah (Radi Allah Anhu) at Mina, 'Uthman (Radi Allah Anhu) happened to meet him. He stopped there and began to talk with him. Uthman (Radi Allah Anhu) said to him: Abu 'Abd al-Rahman (Radi Allah Anhu), should we not marry you to a young girl who may recall to you some of the past of your bygone days; thereupon he said: If you say so, Allah's Messenger (sal-allahu- alleihi-wasallam ) said:
"0 young men, those among you who can support a wife should marry, for it restrains eyes from casting (evil glances). and preserves one from immorality; but those who cannot should devote themselves to fasting for it is a means of controlling sexual desire."

[Sahih Muslim: Volume 8, Book 'Kitab Al-Nikah', Number 3233]
Abdullah (b. Mas'ud) (Radi Allah Anhu) reported that Allah's Messenger (sal-allahu- alleihi-wasallam ) said to us:
"O young men, those among you who can support a wife should marry, for it restrains eyes (from casting evil glances) and preserves one from immorality; but he who cannot afford It should observe fast for it is a means of controlling the sexual desire."

Do not marry the idolatresses until they Believe

[2. Surah Al-Baqarah : Ayah 221]
And do not marry the idolatresses until they believe, and certainly a believing maid is better than an idolatress woman, even though she should please you; and do not give (believing women) in marriage to idolaters until they believe, and certainly a believing servant is better than an idolater, even though he should please you; these invite to the fire, and Allah invites to the garden and to forgiveness by His will, and makes clear His communications to men, that they may be mindful.

Do not marry woman whom your fathers married

[4. Surah An-Nisaa : Ayah 22]
And marry not woman whom your fathers married, except what has already passed; this surely is indecent and hateful, and it is an evil way.

What Allah has Forbidden to you?

[4. Surah An-Nisaa : Ayah 23]
Forbidden to you are your mothers and your daughters and your sisters and your paternal aunts and your maternal aunts and brothers' daughters and sisters' daughters and your mothers that have suckled you and your foster-sisters and mothers of your wives and your step-daughters who are in your guardianship, (born) of your wives to whom you have gone in, but if you have not gone in to them, there is no blame on you (in marrying them), and the wives of your sons who are of your own loins and that you should have two sisters together, except what has already passed; surely Allah is Forgiving, Merciful.

Men are maintainers of Women

[4. Surah An-Nisaa : Ayah 34]
Men are the maintainers of women because Allah has made some of them to excel others and because they spend out of their property; the good women are therefore obedient, guarding the unseen as Allah has guarded; and (as to) those on whose part you fear desertion, admonish them, and leave them alone in the sleeping-places and beat them; then if they obey you, do not seek a way against them; surely Allah is High, Great.

Make Smooth Relation between Husband & Wife

[4. Surah An-Nisaa : Ayah 35]
And if you fear a breach between the two, then appoint judge from his people and a judge from her people; if they both desire agreement, Allah will effect harmony between them, surely Allah is Knowing, Aware.
