Zirr reported that he heard the Messenger of Allah ﷺ say, "Any Muslim man who fights in the cause of Allah for even the brief span between two milkings of a she-camel has earned Paradise. Whoever sincerely asks Allah for martyrdom and then dies or is killed will receive the reward of a martyr. Whoever sustains a wound in the cause of Allah, or suffers any injury, will come on the Day of Resurrection with that wound flowing more abundantly than ever, its color like saffron and its fragrance like musk. And whoever is wounded in the cause of Allah bears the seal of the martyrs."
أخبرنا يوسف بن سعيد قال سمعت حجاجا أنبأنا ابن جريج قال حدثنا سليمان بن موسى قال حدثنا مالك بن يخامر أن
أنه سمع رسول الله ﷺ يقول من قاتل في سبيل الله عز وجل من رجل مسلم فواق ناقة وجبت له الجنة ومن سأل الله القتل من عند نفسه صادقا ثم مات أو قتل فله أجر شهيد ومن جرح جرحا في سبيل الله أو نكب نكبة فإنها تجيء يوم القيامة كأغزر ما كانت لونها كالزعفران وريحها كالمسك ومن جرح جرحا في سبيل الله فعليه طابع الشهداء
