Abu Huraira reported
A person came to the Messenger of Allah (ﷺ) and said: Messenger of Allah, what do you think if a man comes to me in order to appropriate my possession? He (the Holy Prophet) said: Don't surrender your possession to him. He (the inquirer) said: If he fights me? He (the Holy Prophet) remarked: Then fight (with him). He (the inquirer) again said: What do you think if I am killed? He (the Holy Prophet) observed: You would be a martyr. He (the inquirer) said: What do you think of him (Messenger of Allah) If I kill him. He (the Holy Prophet) said: he would be in the Fire.
It is narrated on the authority of Thabit, that when 'Abdullah b. 'Amr and 'Anbasa b. Abi Sufyan were about to fight against each other, Khalid b. 'As rode to 'Abdullah b. 'Amr and persuaded him (not to do so). Upon this Abdullah b. 'Amr said
Are you not aware that the Messenger of Allah (ﷺ) had observed : " He who died in protecting his property is a martyr." This hadith has been narrated by Muhammad b. Hatim , Muhammad b. Bakr , Ahmad b. 'Uthman Naufali , Abu 'Asim , Ibn Juraij.
