[Machine] "From Abu Sahr, he said: 'If they do not bring four witnesses for it, then they are the liars before Allah' ('whoever accuses a Muslim and does not bring four witnesses for it, then he is to receive the punishment of slander')."  

الطبراني:١٩٥٨٩حَدَّثَنَا عَمْرُو بْنُ أَبِي الطَّاهِرِ بْنِ السَّرْحِ الْمِصْرِيُّ ثنا سَعِيدُ بْنُ أَبِي مَرْيَمَ ثنا رِشْدِينُ بْنُ سَعْدٍ

عَنْ أَبِي صَخْرٍ {لَوْلَا جَاءُوا عَلَيْهِ بِأَرْبَعَةِ شُهَدَاءَ فَإِذْ لَمْ يَأْتُوا بِالشُّهَدَاءِ فَأُولَئِكَ عِنْدَ اللهِ هُمُ الْكَاذِبُونَ} «كُلُّ مَنْ قَذَفَ مُسْلِمًا ثُمَّ لَمْ يَأْتِ بِأَرْبَعَةِ شُهَدَاءَ فَهُوَ قَاذِفٌ عَلَيْهِ حَدُّ الْقَذْفِ»

Collected by Qurʾān
quran:24:13

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.  

Why did they, that is, this band ˹of accusers˺, not produce four witnesses to it?, who had witnessed it. And since they did not produce the witnesses, those, in God’s sight, in His judgement, they are liars, in this ˹matter˺.
القرآن:٢٤:١٣

لَوْلَا جَاءُوا عَلَيْهِ بِأَرْبَعَةِ شُهَدَاءَ ۚ فَإِذْ لَمْ يَأْتُوا بِالشُّهَدَاءِ فَأُولَٰئِكَ عِنْدَ اللَّهِ هُمُ الْكَاذِبُونَ  

{لولا} هلا {جاءُوا} أي العصبة {عليه بأربعة شهداء} شاهدوه {فإذا لم يأتوا بالشهداء فأولئك عند الله} أي في حكمه {هم الكاذبون} فيه.
