Sahih Muslim 1045 b
Salim b. 'Abdullah reported on the authority of his father that the Messenger of Allah (ﷺ) gave to 'Umar b. Khattab some gift. Umar said to him:
Messenger of Allah, give it to one who needs it more than I. Upon this the Messenger of Allah (ﷺ) said: Take it; either keep it with you or give it as a charity, and whatever comes to you in the form of this type of wealth, without your being avaricious or begging for it, accept it, but in other circumstances do not let your heart hanker after it. And it was on account of this that Ibn 'Umar never begged anything from anyone, nor refused anything given to him.
وَحَدَّثَنِي أَبُو الطَّاهِرِ، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي عَمْرُو بْنُ الْحَارِثِ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُعْطِي عُمَرَ بْنَ الْخَطَّابِ - رضى الله عنه - الْعَطَاءَ فَيَقُولُ لَهُ عُمَرُ أَعْطِهِ يَا رَسُولَ اللَّهِ أَفْقَرَ إِلَيْهِ مِنِّي ‏.‏ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ خُذْهُ فَتَمَوَّلْهُ أَوْ تَصَدَّقْ بِهِ وَمَا جَاءَكَ مِنْ هَذَا الْمَالِ وَأَنْتَ غَيْرُ مُشْرِفٍ وَلاَ سَائِلٍ فَخُذْهُ وَمَا لاَ فَلاَ تُتْبِعْهُ نَفْسَكَ ‏"‏ ‏.‏ قَالَ سَالِمٌ فَمِنْ أَجْلِ ذَلِكَ كَانَ ابْنُ عُمَرَ لاَ يَسْأَلُ أَحَدًا شَيْئًا وَلاَ يَرُدُّ شَيْئًا أُعْطِيَهُ ‏.‏
