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؟ قَالَ «بَعَثَنِي رَسُولُ اللَّهِ ﷺ إِلَى رَجُلٍ نَكَحَ امْرَأَةَ أَبِيهِ فَأَمَرَنِي أَنْ أَضْرِبَ عُنُقَهُ وَآخُذَ مَالَهُ»
