Whoever shoots an arrow in the path of Allah has the equivalent of freeing a slave

It is narrated from Sayyiduna Abu Najih al-Sulami (may Allah be pleased with him) that he said: 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 cause of Allah will have a reward equal to freeing a slave, and whoever makes an arrow reach (the enemy) in the cause of Allah will have a rank in Paradise." So (that day) I made sixteen arrows reach (the enemy).
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), because this Abu Najih is in fact Amr bin Abasah al-Sulami.

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that he said: We were with the Messenger of Allah (peace and blessings be upon him) at Ta'if on the occasion of the Battle of Hunayn. When he (peace and blessings be upon him) reached al-Ji'ranah, he (peace and blessings be upon him) distributed silver among the people.
This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
