Sorry for replying so late to your comments; but I have been plagued with very serious personal issues so do not want to write when not in proper frame of mind. I’ll be brief and to-the point right away.
YOU: Dear Ijlal, you are right marry singles among you means you(the central authority) should marry singles among you...for whatever reason lets not discuss that for now... But how come here you are NOT leaving the context behind like 4:3? The same rules should apply there, shouldn't it?
ME: Sister, I am neither trying to write the QXP again nor find myself competent enough to do so. As such, my starting point is The Quran as translated in the QXP.
I am willing to accept your version of the interpretation of verse 4:3, but that does not prove what is neither ordained nor prohibited (in clear terms) in The Quran becomes Haraam, unless there is some other principle described by which we can declare something as Haraam. For example, Allah (SWT) has not declared eating of flesh of dogs, cats, wolves, hyenas, etc. as Haraam in any verse, but has given us a clear principle. Indeed the flesh of these animals is Haraam because in verse 5:1 Allah (SWT) declared a very clear principle: “…Permitted for you for food are all plant eating livestock with the exceptions named (5:3).” So only herbivores with the exception of swine are Halaal. Furthermore, even the Halaal animals become haraam if other principles (also described clearly) apply. I cite this example to show you how clearly Allah (SWT) prohibits what is Haraam.
Please do not forget labeling something lawful as unlawful, and vice versa, is a grave sin in itself; so we must be careful.
As for verse 24:32, I never said it is the responsibility of the central authority to marry off singles. All I said was Allah (SWT) is advising The Exalted Prophet to ADVISE the people to marry off the singles… All I wanted to show was this Ayat is not a direct command to individuals; the central idea behind this Ayat in my opinion is that a society with many unmarried adults is not being encouraged. It is not addressed to individuals to be interpreted that one can marry only one who is single. If that was the case, then definitely, this Ayat alone would have been enough to prove prohibition of polygamy.
