3144. It was narrated from Shurāḥbīl bin As-Simṭ that he said to 'Amr bin 'Abasah: "O 'Amr! Tell us a Hadīth that you heard from the Messenger of Allāh ﷺ." He said: "I heard the Messenger of Allāh ﷺ say: 'Whoever develops one gray hair in the cause of Allāh, Most High, it will be light for him on the Day of Resurrection. Whoever shoots an arrow in the cause of Allāh, 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.'" (Ṣaḥīḥ)
