It is narrated from Sayyiduna Amr bin Abasah (may Allah be pleased with him) that we besieged the fortress of Ta'if, and I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever shoots an arrow in the way of Allah will have a reward equal to freeing a slave." The narrator said: That day I shot sixteen arrows. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. It also has a supporting narration (shahid) from Sayyiduna Amr bin Abasah (may Allah be pleased with him).
