The Messenger of Allah ﷺ sent for me and said, "Put on your clothes and your weapons, then come to me."I came to him while he was performing ablution. He raised his eyes to look at me, then lowered them, and said, "I intend to send you out in command of an army. Allah will keep you safe and grant you spoils, and I will allot you a generous share of wealth."I said, "Messenger of Allah, I did not embrace Islam for the sake of wealth. Rather, I embraced Islam out of desire for Islam itself, and to be with the Messenger of Allah ﷺ."The Messenger of Allah ﷺ replied, "Amr, how excellent is righteous wealth in the hands of a righteous man."
بعث إلي رسول الله ﷺ فقال: خذ عليك ثيابك وسلاحك، ثم ائتني. فأتيته وهو يتوضأ، فصعد في النظر ثم طأطأه فقال: إني أريد أن أبعثك على جيش فيسلمك الله ويغنمك، وأزعب لك من المال زعبة صالحة. قال: فقلت: يا رسول الله، ما أسلمت من أجل المال، ولكني أسلمت رغبة في الإسلام، وأن أكون مع رسول الله ﷺ، فقال رسول الله ﷺ: يا عمرو نعما بالمال الصالح للرجل الصالح.
Ahmad (17763), Tabarani in al-Awsat (3213), Ibn Hibban (3210), who graded it sahih, and Hakim (2/632) all narrated it through the route of Musa bin Ali, from his father, who said, "I heard Amr bin As say," then he mentioned it. Its chain is sahih, and Hakim also graded it sahih.Musa bin Ali, with the diminutive form of the name, is the son of Rabah al-Lakhmi, one of the men of Muslim's chain of narrators. He was declared trustworthy by Ibn Main, Ahmad, Nasai, Ibn Saad, and a group of others.Ibn Hibban said, "Ali bin Rabah heard this report from Amr bin As, and he also heard it from Abu Qays instead of Amr, from Amr, and both routes are preserved."As for his statement, "azaba zaabatan," with the letters za and ayn, it means giving or granting. It is said, "zaaba lahu min malihi zaabatan," meaning he gave him a portion of it. Az-zab refers to a portion of wealth.
