Rules in islam about dating
Both the groom and the bride are to consent to the marriage of their own free wills.
The actual rules of marriage and divorce (often part of Personal Status Laws) can differ from country to country, based on codified law and the school of jurisprudence that is largely followed in that country.
In addition to the usual marriage until death or divorce, there is a different fixed-term marriage known as zawāj al-mutʻah ("temporary marriage") permitted only by the Twelver branch of Shia Islam for a pre-fixed period.
There is also Nikah Misyar, a non-temporary marriage with the removal of some conditions permitted by some Sunni Muslims, which usually amount to the wife waiving her right to sustenance from her husband.
Islam is totally opposed to monasticism and celibacy.
In Pre-Islamic Arabia a variety of different marriage practices existed.
