وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ مِنْ قَذْفَ مَمْلُوكَهُ يُقَامُ عَلَيْهِ اَلْحَدُّ يَوْمَ اَلْقِيَامَةِ, إِلَّا أَنْ يَكُونَ كَمَا قَالَ } مُتَّفَقٌ عَلَيْهِ [1] .
Abu Hurairah (RAA) narrated that the Messenger of Allah (ﷺ) said: "He who accuses his slave of committing adultery (without proof) will be punished with the prescribed penalty on the Day of Resurrection unless it is (true) as he said." Agreed upon.
