And those who launch a charge against chaste women, and produce not four witnesses (to support their allegations),- flog them with eighty stripes; and reject their evidence ever after: for such men are wicked transgressors;-

Why did they not bring four witnesses to prove it? When they have not brought the witnesses, such men, in the sight of Allah, (stand forth) themselves as liars!

凡告发贞节的妇女，而不能举出四个男子为见证者， 你们应当把每个人打八十鞭，并且永远不可接受他们的见证。这等人是罪人。

他们为何不举出四个见证来证明这件事呢？他们没有举出四个见证， 所以在真主看来他们是说谎的。
