'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 weapons 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. He then 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 (legitimately acquired) wealth is very excellent for a righteous man!'"  

بَعَثَ إِلَيَّ النَّبِيُّ ﷺ 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 ﷺ فَقَالَ يَا عَمْرُو نِعْمَ الْمَالُ الصَّالِحِ لِلْمَرْءِ الصَّالِحِ
