In the name of Allah, the Most Gracious, the Most Merciful.
Quran: Chapter 4, ‘Lan Tanalu’ ‘By no means shall you attain’, Sura: 4 ‘An-Nisa’ ‘The Women’, Verse: 24
Verse 24: Also (forbidden are) women already married, except those whom your right hands possess. Thus Allah has ordained for you. All others are lawful, provided you seek (them in marriage) with Mahar (bridal-money given by the husband to his wife at the time of marriage) from your property, desiring wedlock chastity, not debauchery (committing illegal sexual intercourse), so with those of whom you have enjoyed sexual relations, give them their Mahar as prescribed, you agree mutually (husband agree to give more or the wife agree not to take), there is not sin on you. Surely, Allah is Ever All-Knowing, All- Wise.
Notes by samia2010oct: Women already married are forbidden, except those whom your right hands possess. ‘Your right hands possess’ means women captured in war. All others, except women told in Verse 23 of Sura 4 ‘An-Nisa’, are lawful for a man provided he marries the women properly asking their willingness for marriage, giving them Mahar (bridal-money given by the husband to his wife at the time of marriage) from his property, and solemnizing in front of the witnesses. Debauchery in sexual relations (that is committing illegal sexual intercourse) is strictly forbidden. So the already married couples where the husbands have not given bridal-money to their wives yet must give their wives their Mahar as prescribed by Allah. If a couple agrees mutually that 1) the husband agrees to give more wealth than agreed earlier to wife as bridal-money or 2) the wife agrees not to take Mahar at all from her husband both such situations are acceptable by Allah. In such a mutual agreement there is no sin. Surely, Allah is Ever All-Knowing, All- Wise. Allah knows if any one is forcing the other one or both are going according to Allah’s Orders.
Difficult words: Debauchery: wickedness, sin, dishonesty.
It is Big Sin Gunaahe Kabira for men and women to have sexual relations out of marriage and it is Big Sin Gunaahe Kabira for men not to give bridal money to their wives.
