Dear Readers,
After careful revaluation of 33:50 and 4:23 it appears that the marriage of cousins is permitted among believers. The last prophet was the only person who was permitted to take wifes who had decreed themselves to him without a dowry.
Marriage of Cousins permitted
4:23 Forbidden for you are your mothers, your daughters, your sisters, your fathers' sisters, your mothers' sisters, the daughters of your brother, and the daughters of your sister, your foster mothers who suckled you, your sisters from suckling, the mothers of your wives, and your step-daughters residing in your homes from your wives which you have already consummated the marriage with; if you have not consummated the marriage then there is no sin upon you; and the wives of your sons that are from your seed, and that you join between two sisters except what has already been done. God is Forgiving, Compassionate.
4:24 The women who are already married, except those whom you have contractual rights, God's book is over you; and permitted for you is what is beyond this, if you are seeking with your money to be protected and not for illicit sex. As for those whom you have already had joy with them, then you shall give them their wage as an obligation. There is no sin upon you for what you agree to after the obligation. God is Knowledgeable, Wise.
No dowry is necessary:-
33:50 O prophet, We have made lawful for you the wives to whom you have already given their dowry, and the one who is committed to you by oath, as granted to you by God, and the daughters of your father's brothers, and the daughters of your father's sisters, and the daughters of your mother's brothers, and the daughters of your mother's sisters, of whom they have emigrated with you. Also, the acknowledging woman who had decreed herself to the prophet, the prophet may marry her if he wishes, as a privilege given only to you and not to those who acknowledge. We have already decreed their rights in regard to their spouses and those who are still dependants. This is to spare you any hardship. God is Forgiver, Compassionate. - Edip/layth
33:50 O prophet, we made lawful for you your wives to whom you have paid their due dowry, or what you already have, as granted to you by GOD. Also lawful for you in marriage are the daughters of your father's brothers, the daughters of your father's sisters, the daughters of your mother's brothers, the daughters of your mother's sisters, who have emigrated with you. Also, if a believing woman gave herself to the prophet - by forfeiting the dowry - the prophet may marry her without a dowry, if he so wishes. However, her forfeiting of the dowry applies only to the prophet, and not to the other believers. We have already decreed their rights in regard to their spouses or what they already have. This is to spare you any embarrassment. GOD is Forgiver, Most Merciful. -Rashad Khalifa
My misinterpretation came about because of the lack of study in this particular subject. Marriage is the last thing on my mind (because of my age and other circumstances)
Peace,
