Sunan an-Nasa'i, Book 25, Hadith 57 (In-Book) ⓘ

Mu'adh bin Jabal said that he heard the Prophet say: "Whoever fights in the cause of Allah, the Mighty and Sublime, for the length of time between two milkings of a she-camel, Paradise is guaranteed for him. Whoever asks Allah to be killed (in Jihad) sincerely, from his heart, then he dies or is killed, he will have the reward of a martyr. Whoever is wounded or injured in the cause of Allah, it will come on the Day of Resurrection bleeding the most it ever bled, but its color will be like saffron, and its fragrance will be like musk. Whoever is wounded in the cause of Allah, upon him is the seal of the martyrs."

أَخْبَرَنَا يُوسُفُ بْنُ سَعِيدٍ، قَالَ سَمِعْتُ حَجَّاجًا، أَنْبَأَنَا ابْنُ جُرَيْجٍ، قَالَ حَدَّثَنَا سُلَيْمَانُ بْنُ مُوسَى، قَالَ حَدَّثَنَا مَالِكُ بْنُ يُخَامِرَ، أَنَّ مُعَاذَ بْنَ جَبَلٍ، حَدَّثَهُمْ أَنَّهُ، سَمِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ مَنْ قَاتَلَ فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ مِنْ رَجُلٍ مُسْلِمٍ فُوَاقَ نَاقَةٍ وَجَبَتْ لَهُ الْجَنَّةُ وَمَنْ سَأَلَ اللَّهَ الْقَتْلَ مِنْ عِنْدِ نَفْسِهِ صَادِقًا ثُمَّ مَاتَ أَوْ قُتِلَ فَلَهُ أَجْرُ شَهِيدٍ وَمَنْ جُرِحَ جُرْحًا فِي سَبِيلِ اللَّهِ أَوْ نُكِبَ نَكْبَةً فَإِنَّهَا تَجِيءُ يَوْمَ الْقِيَامَةِ كَأَغْزَرِ مَا كَانَتْ لَوْنُهَا كَالزَّعْفَرَانِ وَرِيحُهَا كَالْمِسْكِ وَمَنْ جُرِحَ جُرْحًا فِي سَبِيلِ اللَّهِ فَعَلَيْهِ طَابَعُ الشُّهَدَاءِ ‏" ‏ ‏.‏
