“The Messenger of Allah ﷺ sent me to a man who had married his father's wife after he died, to strike his neck (execute him) and confiscate his wealth.”  

بَعَثَنِي رَسُولُ اللَّهِ ﷺ إِلَى رَجُلٍ تَزَوَّجَ امْرَأَةَ أَبِيهِ أَنْ أَضْرِبَ عُنُقَهُ وَأُصَفِّيَ مَالَهُ  

[Machine] My uncle met me with a flag, so I asked him, "Where are you headed?" He said, "The Prophet ﷺ sent me to a man who married his father's wife, and commanded me to kill him."  

لَقِيَنِي عَمِّي وَمَعَهُ رَايَةٌ فَقُلْتُ أَيْنَ تُرِيدُ؟ فَقَالَ بَعَثَنِي النَّبِيُّ ﷺ إِلَى رَجُلٍ تَزَوَّجَ امْرَأَةَ أَبِيهِ فَأَمَرَنِي أَنْ أَقْتُلَهُ  

"I met my maternal uncle who was carrying a flag (for an expedition) and I said: 'Where are you going?' He said: 'The Messenger of Allah is sending me to a man who has married his father's wife after he died, to strike his neck or kill him.'" (Using translation from Nasāʾī 3331)   

لَقِيتُ خَالِي وَمَعَهُ الرَّايَةُ قُلْتُ أَيْنَ تُرِيدُ؟ قَالَ «بَعَثَنِي النَّبِيُّ ﷺ إِلَى رَجُلٍ تَزَوَّجَ امْرَأَةَ أَبِيهِ مِنْ بَعْدِهِ فَأَمَرَنِي أَنْ أَضْرِبَ عُنُقَهُ»  

I met my uncle who was carrying a standard. I asked him: Where are you going? He said: The Messenger of Allah ﷺ has sent me to a man who has married his father's wife. He has ordered me to cut off his head and take his property. (Using translation from Abū Dāʾūd 4457)   

لَقِيتُ عَمِّي وَمَعَهُ رَايَةٌ فَقُلْتُ أَيْنَ تُرِيدُ؟ فَقَالَ «بَعَثَنِي رَسُولُ اللهِ ﷺ إِلَى رَجُلٍ تَزَوَّجَ امْرَأَةَ أَبِيهِ وَأَمَرَنِي أَنْ أَقْتُلَهُ»  

"عَنِ الْبَراءِ أَنَّ النَّبِيَّ ﷺ أَرْسَلَهُ إِلَى رَجُلٍ تَزَوَّجَّ امْرَأَةَ أَبِيهِ، فَأَمَرَهُ أَنْ يَأتِيَ بِرَأسِهِ".
