Sunan Ibn Majah, Book 20, Hadith 2679 (In-Book) ⓘ
It was narrated from Ibn `Umar that the Messenger of Allah said: “If a man's property is targeted, and he is fought and fights back and is killed, he is a martyr.”
حَدَّثَنَا الْخَلِيلُ بْنُ عَمْرٍو، حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ، حَدَّثَنَا يَزِيدُ بْنُ سِنَانٍ الْجَزَرِيُّ، عَنْ مَيْمُونِ بْنِ مِهْرَانَ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أُتِيَ عِنْدَ مَالِهِ فُقُوتِلَ فَقَاتَلَ فَقُتِلَ فَهُوَ شَهِيدٌ " .
