Sa'id bin Zaid (RAA) narrated that the Messenger of Allah (ﷺ) said:

"Whoever is killed while protecting his property, he is a martyr." Related by the four Imams and At-Tirmidhi graded it as Sahih.

وَعَنْ سَعِيدِ بْنِ زَيْدٍ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{

مِنْ قُتِلَ دُونَ مَالِهِ فَهُوَ شَهِيدٌ

} رَوَاهُ اَلْأَرْبَعَةُ, وَصَحَّحَهُ اَلتِّرْمِذِيُّ [1]‏
