A man of Bakr ibn Layth came to the Prophet ﷺ and made confession four times that he had committed fornication with a woman, so he had a hundred lashes administered to him. The man had not been married. He then asked him to produce proof against the woman, and she said: I swear by Allah, Messenger of Allah, that he has lied. Then he was given the punishment of eighty lashes of falsehood. (Using translation from Abū Dāʾūd 4467)
أَنَّ رَجُلًا مِنْ بَنِي لَيْثِ بْنِ بَكْرِ أَتَى النَّبِيَّ ﷺ فَأَقَرَّ أَنَّهُ زِنَا بِامْرَأَةٍ أَرْبَعَ مَرَّاتٍ فَجَلَدَهُ مِائَةً وَكَانَ بِكْرًا وَسَأَلَهُ الْبَيِّنَةَ عَلَى الْمَرْأَةِ فَقَالَتِ الْمَرْأَةُ «كَذَبَ وَاللهِ يَا رَسُولَ اللهِ فَجَلَدَهُ جَلْدَ الْفِرْيَةِ ثَمَانِينَ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا حَدِيثٌ مُنْكَرٌ
