“Were it not for a word that I heard from 'Amr bin Hamiq Khuza'i, I would have separated the head of Al-Mukhtar from his body. I heard him saying: “The Messenger of Allah ﷺ said: 'If a man trusts someone with his life then he kills him, he will carry a banner of treachery on the day of Resurrection.'” (Using translation from Ibn Mājah 2688)  

قَالَ رَسُولُ اللهِ ﷺ «مَنْ آمَنَ رَجُلًا عَلَى دَمِهِ فَقَتَلَهُ فَإِنَّهُ يُحْمَلُ لِوَاءَ غَدِرٍ يَوْمَ الْقِيَامَةِ»  

[Machine] I heard the Messenger of Allah ﷺ saying: "Whoever believes in a person and then kills him, he will be given the flag of treachery on the Day of Resurrection."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ آمَنَ رَجُلًا عَلَى نَفْسِهِ ثُمَّ قَتَلَهُ أُعْطِيَ لِوَاءَ غَدْرٍ يَوْمَ الْقِيَامَةِ»  

[Machine] I heard the Messenger of Allah, ﷺ , saying, "When a person seeks refuge with another person and then kills him, he will be raised with the banner of treachery on the Day of Resurrection." And the wording is for Jacob.  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «إِذَا اطْمَأَنَّ الرَّجُلُ إِلَى الرَّجُلِ ثُمَّ قَتَلَهُ رُفِعَ لَهُ لِوَاءُ غَدْرٍ يَوْمَ الْقِيَامَةِ» وَاللَّفْظُ لِيَعْقُوبَ
