24:13
لَّوْلَا جَآءُو عَلَيْهِ بِأَرْبَعَةِ شُهَدَآءَ ۚ فَإِذْ لَمْ يَأْتُوا۟ بِٱلشُّهَدَآءِ فَأُو۟لَـٰٓئِكَ عِندَ ٱللَّهِ هُمُ ٱلْكَـٰذِبُونَ
lawlā jāū ʿalayhi bi-arbaʿati shuhadāa fa-idh lam yatū bil-shuhadāi fa-ulāika ʿinda l-lahi humu l-kādhibūna
And why did the accusers not bring four witnesses to it? If they cannot produce such witnesses, they are the liars in God’s eyes.
Why did they not produce four witnesses? Since they (the slanderers) have not produced witnesses! Then with Allâh they are the liars.
