"If somebody slanders his slave (by accusing him of committing illegal sexual intercourse) and the slave is innocent from what he says, Allah will impose the punishment upon him on the Day of Resurrection, unless it is as he said about him." (Using translation from Tirmidhī 1947)   

أَنَّهُ حَدَّثَهُ قَالَ قَالَ أَبُو الْقَاسِمِ ﷺ نَبِيُّ التَّوْبَةِ «مَنْ قَذَفَ مَمْلُوكَهُ بَرِيئًا مِمَّا قَالَ أَقَامَ عَلَيْهِ الْحَدَّ يَوْمَ الْقِيَامَةِ إِلَّا أَنْ يَكُونَ كَمَا قَالَ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا حَدِيثٌ جَيِّدٌ  

[Machine] "Whoever mistreats his slave, he will have a punishment on the Day of Judgment from Allah. If He wishes, He will take it from him, and if He wishes, He will forgive him."  

«مَنْ قَذَفَ مَمْلُوكَهُ كَانَ لِلَّهِ فِي ظَهْرِهِ حَدٌّ يَوْمَ الْقِيَامَةِ إِنْ شَاءَ أَخَذَهُ وَإِنْ شَاءَ عَفَا عَنْهُ»
