'Amr ibn al-'As said, "The Prophet, may Allah bless him and grant him peace, sent for me. He commanded me to put on my clothes and arms and come to him. I did that and came to him while he was doing wudu'. He looked at me and then lowered his eyes. then he said, ''Amr, I want to put you in charge of an army and Allah will give you booty. I will give you a correct portion of the spoils.' I said, 'I did not become Muslim out of the desire for property. I became Muslim out of the desire for Islam and so that I would be with the Messenger of Allah, may Allah bless him and grant him peace.' He said, ''Amr! Sound property is very excellent for a sound man!'"

حَدَّثَنَا عَبْدُ اللهِ بْنُ يَزِيدَ، قَالَ‏:‏ حَدَّثَنَا مُوسَى بْنُ عَلِيٍّ قَالَ‏:‏ سَمِعْتُ أَبِي يَقُولُ‏:‏ سَمِعْتُ عَمْرَو بْنَ الْعَاصِ قَالَ‏:‏ بَعَثَ إِلَيَّ النَّبِيُّ صلى الله عليه وسلم فَأَمَرَنِي أَنْ آخُذَ عَلَيَّ ثِيَابِي وَسِلاَحِي، ثُمَّ آتِيهِ، فَفَعَلْتُ فَأَتَيْتُهُ وَهُوَ يَتَوَضَّأُ، فَصَعَّدَ إِلَيَّ الْبَصَرَ ثُمَّ طَأْطَأَ، ثُمَّ قَالَ‏:‏ يَا عَمْرُو، إِنِّي أُرِيدُ أَنْ أَبْعَثَكَ عَلَى جَيْشٍ فَيُغْنِمُكَ اللَّهُ، وَأَرْغَبُ لَكَ رَغْبَةً مِنَ الْمَالِ صَالِحَةً، قُلْتُ‏:‏ إِنِّي لَمْ أُسْلِمْ رَغْبَةً فِي الْمَالِ، إِنَّمَا أَسْلَمْتُ رَغْبَةً فِي الإِسْلاَمِ فَأَكُونُ مَعَ رَسُولِ اللهِ صلى الله عليه وسلم، فَقَالَ‏:‏ يَا عَمْرُو، نِعْمَ الْمَالُ الصَّالِحِ لِلْمَرْءِ الصَّالِحِ‏.‏
