Hadiths about the Marriage

Narrated AbuHurayrah Allah’s Messenger (peace be upon him) said, ‘When someone with whose religion and character you are satisfied asks your daughter in marriage, accede to his request. If you do not do so, there will be temptation on Earth and extensive corruption.’
Tirmidhi, Nasa’i and Ibn Majah transmitted it.
Al-Tirmidhi – Hadith 3090

Narrated Umar bin Al-Khattab: I heard Allah’s Apostle saying, “The reward of deeds depends upon the intentions and every person will get the reward according to what he has intended. So whoever emigrated for worldly benefits or for a woman to marry, his emigration was for what he emigrated for.”
Sahih Al-Bukhari – Book 1 Hadith 1

Sex in the view of Islam

Certainly will the believers have succeeded:They who are during their prayer humbly submissive And they who turn away from ill speech And they who are observant of zakah And they who guard their private parts Except from their wives or those their right hands possess, for indeed, they will not be blamed -But whoever seeks beyond that, then those are the transgressors -And they who are to their trusts and their promises attentive And they who carefully maintain their prayers -Those are the inheritors Who will inherit al-Firdaus. They will abide therein eternally.
Surat Al-Mu’minun (The Believers) 23:1-11

And tell the believing women to reduce [some] of their vision and guard their private parts and not expose their adornment except that which [necessarily] appears thereof and to wrap [a portion of] their headcovers over their chests and not expose their adornment except to their husbands, their fathers, their husbands’ fathers, their sons, their husbands’ sons, their brothers, their brothers’ sons, their sisters’ sons, their women, that which their right hands possess, or those male attendants having no physical desire, or children who are not yet aware of the private aspects of women. And let them not stamp their feet to make known what they conceal of their adornment. And turn to Allah in repentance, all of you, O believers, that you might succeed.
Surat An-Nur (The Light) 24:31

Forgiveness

Then Adam received from his Lord [some] words, and He accepted his repentance. Indeed, it is He who is the Accepting of repentance, the Merciful.
Surat Al-Baqarah 2:37

And [recall] when Moses said to his people, “O my people, indeed you have wronged yourselves by your taking of the calf [for worship]. So repent to your Creator and kill yourselves. That is best for [all of] you in the sight of your Creator.” Then He accepted your repentance; indeed, He is the Accepting of repentance, the Merciful.
Surat Al-Baqarah 2:54

But if one fears from the bequeather [some] error or sin and corrects that which is between them, there is no sin upon him. Indeed, Allah is Forgiving and Merciful.
Surat Al-Baqarah 2:182
