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 بَكْرِ بْنِ لَيْثٍ أَتَى النَّبِيَّ ﷺ فَأَقَرَّ أَنَّهُ زَنَى بِامْرَأَةٍ أَرْبَعَ مِرَارٍ فَجُلِدَ مِائَةً وَكَانَ بِكْرًا ثُمَّ سَأَلَهُ الْبَيِّنَةَ عَلَى الْمَرْأَةِ فَقَالَتِ الْمَرْأَةُ كَذَبَ وَاللَّهِ يَا رَسُولَ اللَّهِ فَجَلَدَهُ حَدَّ الْفِرْيَةِ ثَمَانِينَ
