Sunan an-Nasa'i, Volume 3, Book 23, Hadith 2609 (DarusSalam) ⓘ

'Abdullah bin Umar said: "I heard 'Umar, may Allah be pleased with him, say: The Prophet used to give me payment and I would say: Give it to someone who is more, in need of it than I am, until one day he gave me some money and I said to him: Give it to someone who is more in need of it than I am. He said: Take it and keep it or give it in charity. Whatever comes to you of this wealth when you are not hoping for it and not asking for it, take it, and whatever does not, then do not wish for it. "'

أَخْبَرَنَا عَمْرُو بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا الْحَكَمُ بْنُ نَافِعٍ، قَالَ أَنْبَأَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، قَالَ سَمِعْتُ عُمَرَ، رضى الله عنه يَقُولُ كَانَ النَّبِيُّ صلى الله عليه وسلم يُعْطِينِي الْعَطَاءَ فَأَقُولُ أَعْطِهِ أَفْقَرَ إِلَيْهِ مِنِّي حَتَّى أَعْطَانِي مَرَّةً مَالاً فَقُلْتُ لَهُ أَعْطِهِ أَفْقَرَ إِلَيْهِ مِنِّي ‏.‏ فَقَالَ ‏ "‏ خُذْهُ فَتَمَوَّلْهُ وَتَصَدَّقْ بِهِ وَمَا جَاءَكَ مِنْ هَذَا الْمَالِ وَأَنْتَ غَيْرُ مُشْرِفٍ وَلاَ سَائِلٍ فَخُذْهُ وَمَا لاَ فَلاَ تُتْبِعْهُ نَفْسَكَ ‏" ‏ ‏.‏
