'Abdullah bin 'Umar narrated that The Messenger of Allah (ﷺ) said:

“He who is killed while defending his property is considered a martyr.” Related by Abu Dawud An-Nasa’i and At-Tirmidhi who graded it as Sahih.

عَنْ عَبْدِ اَللَّهِ بْنِ عَمْرٍو رَضِيَ اَللَّهُ عَنْهُمَا [1]‏ قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ مِنْ قُتِلَ دُونَ مَالِهِ فَهُوَ شَهِيدٌ } رَوَاهُ أَبُو دَاوُدَ, وَالنَّسَائِيُّ, وَاَلتِّرْمِذِيُّ وَصَحَّحَهُ [2]‏ .‏
