Talking of "interpretations", I'd just saw the declarations of London's imam, on the aftermath of the terrorist attack, and he quoted Quran 5:32; well, kind of, he quoted a sentence of it:
whoever kills a soul unless for a soul or for corruption [done] in the land - it is as if he had slain mankind entirely.
Well then, this is one of those sentences commonly used for al-Taqqyia (deceit on behalf of Islam), but that sentenced isn't even a command to Muslims, just a command "once given" to the Jews. To get the whole picture you need to read from 5:31 to 5:34, and here's what it reads as whole:
31
Then Allah sent a crow searching in the ground to show him how to hide the disgrace of his brother. He said, "O woe to me! Have I failed to be like this crow and hide the body of my brother?" And he became of the regretful.
32
Because of that, We decreed upon the Children of Israel that whoever kills a soul unless for a soul or for corruption [done] in the land - it is as if he had slain mankind entirely. And whoever saves one - it is as if he had saved mankind entirely. And our messengers had certainly come to them with clear proofs. Then indeed many of them, [even] after that, throughout the land, were transgressors.
33
Indeed, the penalty for those who wage war against Allah and His Messenger and strive upon earth [to cause] corruption is none but that they be killed or crucified or that their hands and feet be cut off from opposite sides or that they be exiled from the land. That is for them a disgrace in this world; and for them in the Hereafter is a great punishment,
34
Except for those who return [repenting] before you apprehend them. And know that Allah is Forgiving and Merciful.
Not that beautiful anymore, is it?
