وعن عبد الله بن عمرو بن العاص رضي الله عنهما أن رسول الله صلى الله عليه وسلم قال: "يغفر الله للشهيد كل شيء إلا الدين" ((رواه مسلم)).
The Messenger of Allah (ﷺ) said, "Allah forgives every sin of a martyr, except his debt."[Muslim].Another narration in Muslim is: The Messenger of Allah (ﷺ) said, "Being martyred in the Cause of Allah expiates for everything, except debt."
