"O 'Amr! Tell us a Hadith that you heard from the Messenger of Allah ﷺ." He said: "I heard the Messenger of Allah ﷺ say: 'Whoever develops one gray hair in the cause of Allah, Most High, it will be light for him on the Day of Resurrection. Whoever shoots an arrow in the cause of Allah, Most High, whether it reaches the enemy or not, it will be as if he freed a slave. Whoever frees a believing slave, it will be a ransom for him from the Fire, limb by limb.'" (Using translation from Nasāʾī 3142)
حَدِّثْنَا حَدِيثًا سَمِعْتَهُ مِنْ رَسُولِ اللهِ ﷺ قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ شَابَ شَيْبَةً فِي سَبِيلِ اللهِ كَانَتْ لَهُ نُورًا يَوْمَ الْقِيَامَةِ وَمَنْ رَمَى بِسَهْمٍ فِي سَبِيلِ اللهِ فَبَلَغَ الْعَدُوَّ أَوْ لَمْ يَبْلُغْ كَانَ لَهُ كَعِتْقِ رَقَبَةٍ وَمَنْ أَعْتَقَ رَقَبَةً مُؤْمِنَةً كَانَتْ فِدَاءَهُ مِنَ النَّارِ عُضْوًا بِعُضْوٍ»
