النّور — An-Nur Ayat 13
لَوْلَا جَاۤءُوْ عَلَيْهِ بِاَرْبَعَةِ شُهَدَاۤءَۚ فَاِذْ لَمْ يَأْتُوْا بِالشُّهَدَاۤءِ فَاُولٰۤىِٕكَ عِنْدَ اللّٰهِ هُمُ الْكٰذِبُوْنَ
Lau lā jā'ū ‘alaihi bi'arba‘ati syuhadā'(a), fa iż lam ya'tū bisy-syuhadā'i fa ulā'ika ‘indallāhi humul-kāżibūn(a).
"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."
