أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا خَالِدٌ، قَالَ حَدَّثَنَا حَاتِمٌ، عَنْ عَمْرِو بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏ مَنْ قَاتَلَ دُونَ مَالِهِ فَقُتِلَ فَهُوَ شَهِيدٌ ‏"‏ ‏.‏
Translation
It was narrated from Ibrahim bin Muhammad bin Talhah that he heard 'Abdullah bin 'Amr narrating

From the Prophet [SAW], that he said: "If a person's wealth is sought without right, and he fights (to protect it) and is killed, he is a martyr."
