Ahh Americans...
Don't you know you can't take a sound-bite and claim it sez this or that? You have to read it in the context of the whole Sura. This is not just for the Koran but for ALL historical documents. It is the very basis of research.
Most of all, you have to read the background... about why this thing was said (not given here). There is a story behind every Sura and without it, one is like the donkey who only carries books but never reads them.
Let me help you out:
[Pickthal 66:1] O Prophet! Why bannest thou that which Allah hath made lawful for thee, seeking to please thy wives? And Allah is Forgiving, Merciful.
[Pickthal 66:2] Allah hath made lawful for you (Muslims) absolution from your oaths (of such a kind), and Allah is your Protector. He is the Knower, the Wise.
[Pickthal 66:3] When the Prophet confided a fact unto one of his wives and when she afterward divulged it and Allah apprised him thereof, he made known (to her) part thereof and passed over part. And when he told it her she said: Who hath told thee? He said: The Knower, the Aware hath told me.
[Pickthal 66:4] If ye twain turn unto Allah repentant, (ye have cause to do so) for your hearts desired (the ban); and if ye aid one another against him (Muhammad) then lo! Allah, even He, is his Protecting Friend, and Gabriel and the righteous among the believers; and furthermore the angels are his helpers.
[Pickthal 66:5] It may happen that his Lord, if he divorce you, will give him in your stead wives better than you, submissive (to Allah), believing, pious, penitent, devout, inclined to fasting, widows and maids.
[Pickthal 66:6] O ye who believe! Ward off from yourselves and your families a Fire whereof the fuel is men and stones, over which are set angels strong, severe, who resist not Allah in that which He commandeth them, but do that which they are commanded.
[Pickthal 66:7] (Then it will be said): O ye who disbelieve! Make no excuses for yourselves this day. Ye are only being paid for what ye used to do.
[Pickthal 66:8] O ye who believe! Turn unto Allah in sincere repentance! It may be that your Lord will remit from you your evil deeds and bring you into Gardens underneath which rivers flow, on the day when Allah will not abase the Prophet and those who believe with him. Their light will run before them and on their right hands; they will say: Our Lord! Perfect our light for us, and forgive us! Lo! Thou art Able to do all things.
[Pickthal 66:9] O Prophet! Strive against the disbelievers and the hypocrites, and be stern with them. Hell will be their home, a hapless journey's end.
[Pickthal 66:10] Allah citeth an example for those who disbelieve: the wife of Noah and the wife of Lot, who were under two of Our righteous slaves yet betrayed them so that they (the husbands) availed them naught against Allah and it was said (unto them): Enter the Fire along with those who enter.
[Pickthal 66:11] And Allah citeth an example for those who believe: the wife of Pharaoh when she said: My Lord! Build for me a home with thee in the Garden, and deliver me from Pharaoh and his work, and deliver me from evil-doing folk;
[Pickthal 66:12] And Mary, daughter of 'Imran, whose body was chaste, therefor We breathed therein something of Our Spirit. And she put faith in the words of her Lord and His scriptures, and was of the obedient.
