A man came to the Prophet ﷺ and made acknowledgment before him that he had committed fornication with a woman whom he named. The Messenger of Allah ﷺ sent someone to the woman and he asked her about it. She denied that she had committed fornication. So he gave him the prescribed punishment of lashes and left her.  

عَنِ النَّبِيِّ ﷺ أَنَّ رَجُلاً أَتَاهُ فَأَقَرَّ عِنْدَهُ أَنَّهُ زَنَى بِامْرَأَةٍ سَمَّاهَا لَهُ فَبَعَثَ رَسُولُ اللَّهِ ﷺ إِلَى الْمَرْأَةِ فَسَأَلَهَا عَنْ ذَلِكَ فَأَنْكَرَتْ أَنْ تَكُونَ زَنَتْ فَجَلَدَهُ الْحَدَّ وَتَرَكَهَا  

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.  

أَنَّ رَجُلاً مِنْ بَكْرِ بْنِ لَيْثٍ أَتَى النَّبِيَّ ﷺ فَأَقَرَّ أَنَّهُ زَنَى بِامْرَأَةٍ أَرْبَعَ مَرَّاتٍ فَجَلَدَهُ مِائَةً وَكَانَ بِكْرًا ثُمَّ سَأَلَهُ الْبَيِّنَةَ عَلَى الْمَرْأَةِ فَقَالَتْ كَذَبَ وَاللَّهِ يَا رَسُولَ اللَّهِ فَجَلَدَهُ حَدَّ الْفِرْيَةِ ثَمَانِينَ
