سنن النسائي

It was narrated from Qabus bin Mukhariq that his father said: "I heard Sufyan Ath-Thawri narrating this Hadith. He said: 'A man came to the Prophet (ﷺ) [SAW] and said: "What if a man comes to me and wants to take my wealth?" He said: "Remind him of Allah." He said: "What if he pays no heed?" He said: "Seek the help of the Muslims around you against him." He said: "What if there are no Muslims around me?" He said: "Seek the help of the ruler against him." He said: "What if the ruler is far away from me?" He said: "Fight to defend your wealth until you either become one of the martyrs of the Hereafter, or you protect your wealth (successfully)."
