Sunan Abi Dawud 2541
Narrated Mu'adh ibn Jabal:
The Messenger of Allah (ﷺ) said: If anyone fights in Allah's path as long as the time between two milkings of a she-camel, Paradise will be assured for him. If anyone sincerely asks Allah for being killed and then dies or is killed, there will be a reward of a martyr for him. Ibn al-Musaffa added from here: If anyone is wounded in Allah's path, or suffers a misfortune, it will come on the Day of resurrection as copious as possible, its colour saffron, and its odour musk; and if anyone suffers from ulcers while in Allah's path, he will have on him the stamp of the martyrs.
حَدَّثَنَا هِشَامُ بْنُ خَالِدٍ أَبُو مَرْوَانَ، وَابْنُ الْمُصَفَّى، قَالاَ حَدَّثَنَا بَقِيَّةُ، عَنِ ابْنِ ثَوْبَانَ، عَنْ أَبِيهِ، يَرُدُّ إِلَى مَكْحُولٍ إِلَى مَالِكِ بْنِ يُخَامِرَ أَنَّ مُعَاذَ بْنَ جَبَلٍ، حَدَّثَهُمْ أَنَّهُ، سَمِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏:‏ ‏"‏ مَنْ قَاتَلَ فِي سَبِيلِ اللَّهِ فُوَاقَ نَاقَةٍ فَقَدْ وَجَبَتْ لَهُ الْجَنَّةُ، وَمَنْ سَأَلَ اللَّهَ الْقَتْلَ مِنْ نَفْسِهِ صَادِقًا ثُمَّ مَاتَ أَوْ قُتِلَ فَإِنَّ لَهُ أَجْرَ شَهِيدٍ ‏"‏ ‏.‏ زَادَ ابْنُ الْمُصَفَّى مِنْ هُنَا ‏:‏ ‏"‏ وَمَنْ جُرِحَ جُرْحًا فِي سَبِيلِ اللَّهِ أَوْ نُكِبَ نَكْبَةً فَإِنَّهَا تَجِيءُ يَوْمَ الْقِيَامَةِ كَأَغْزَرِ مَا كَانَتْ، لَوْنُهَا لَوْنُ الزَّعْفَرَانِ، وَرِيحُهَا رِيحُ الْمِسْكِ، وَمَنْ خَرَجَ بِهِ خُرَاجٌ فِي سَبِيلِ اللَّهِ فَإِنَّ عَلَيْهِ طَابَعَ الشُّهَدَاءِ ‏"‏ ‏.‏
