Sahih Muslim 1793
Sahih Muslim · Book 32: The Book of Jihad and Expeditions · The intense wrath of Allah towards the one who was killed by the messenger of Allah (saws)
It has been narrated by Hammam b. Munabbih who said:
حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ ، حَدَّثَنَا مَعْمَرٌ ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " اشْتَدَّ غَضَبُ اللَّهِ عَلَى قَوْمٍ فَعَلُوا هَذَا بِرَسُولِ اللَّهِ صلى الله عليه وسلم " . وَهُوَ حِينَئِذٍ يُشِيرُ إِلَى رَبَاعِيَتِهِ وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " اشْتَدَّ غَضَبُ اللَّهِ عَلَى رَجُلٍ يَقْتُلُهُ رَسُولُ اللَّهِ فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ " .
This is what has been related to us by Abu Huraira from the Messenger of Allah (ﷺ). (With this introduction) he narrated a number of traditions. One of these was that the Messenger of Allah (ﷺ) said: Great is the wrath of Allah upon a people who have done this to the Messenger of Allah (ﷺ), and he was at that time pointing to his front teeth. The Messenger of Allah (ﷺ) also said: Great is the wrath of Allah upon a person who has been killed by the Messenger of Allah (ﷺ) in the way of Allah, the Exalted and Glorious.
