لَّوۡلَا جَآءُو عَلَيۡهِ بِأَرۡبَعَةِ شُهَدَآءَۚ فَإِذۡ لَمۡ يَأۡتُواْ بِٱلشُّهَدَآءِ فَأُوْلَـٰٓئِكَ عِندَ ٱللَّهِ هُمُ ٱلۡكَٰذِبُونَ
Law laa jaaa'oo 'alaihi bi-arba'ati shuhadaaa'; fa iz lam yaatoo bishshuhadaaa'i fa ulaaa 'ika 'indal laahi humul kaaziboon
English Translation
Why did they [who slandered] not produce for it four witnesses? And when they do not produce the witnesses, then it is they, in the sight of Allah, who are the liars
