It was narrated from Sulaiman bin Buraidah that his father said: "The Messenger of Allah SAW said: 'Whoever is killed defending his wealth, he is a martyr'."
This hadith also teaches us about self-sacrifice and courage in the face of danger or adversity. It encourages us to stand up for what we believe in even if it means putting our lives at risk or sacrificing something we hold dear such as our possessions or money. We should strive to do what is right even if it comes with a cost because ultimately we will be rewarded for our efforts both here on earth and in the hereafter.
