Jami` at-Tirmidhi 2463
'Urwah bin Az-Zubair and Ibn Musayyab narrated that Hakim bin Hizam said:
"I (once) asked the Messenger of Allah (s.a.w) (for something) and he gave it to me. Then I asked him (again) and he gave it to me. Then I asked  him (again) and he gave it to me. Then I asked  him (again), so he gave it to me. Then he said: 'O Hakim! Indeed this wealth is green and sweet, so whoever takes it without asking for it, he will be blessed in it. And whoever takes it, insisting upon it, he will not be blessed in it. He is like the one who eats but does not get satisfied and contended. And the upper hand (giving) is better than the lower hand (receiving)." So Hakim said: "I said: 'O  Messenger of Allah! By the One who sent you with the Truth! I shall not ask anyone for anything  after you until I depart the world.'"So Abu Bakr used to call Hakim to give him something, but he refused to accept it. Then 'Umar  called him to give to him, but he refused to accept it. So 'Umar said: "O you Muslims! I would like you to bear witness that I presented Hakim with his due of these spoils of war but he refused to accept it." So Hakim never asked anyone of the people for anything after the Messenger of Allah, until he died.
حَدَّثَنَا سُوَيْدٌ، أَخْبَرَنَا عَبْدُ اللَّهِ، عَنْ يُونُسَ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، وَابْنِ الْمُسَيَّبِ، أَنَّ حَكِيمَ بْنَ حِزَامٍ، قَالَ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فَأَعْطَانِي ثُمَّ سَأَلْتُهُ فَأَعْطَانِي ثُمَّ سَأَلْتُهُ فَأَعْطَانِي ثُمَّ قَالَ ‏
"‏ يَا حَكِيمُ إِنَّ هَذَا الْمَالَ خَضِرَةٌ حُلْوَةٌ فَمَنْ أَخَذَهُ بِسَخَاوَةِ نَفْسٍ بُورِكَ لَهُ فِيهِ وَمَنْ أَخَذَهُ بِإِشْرَافِ نَفْسٍ لَمْ يُبَارَكْ لَهُ فِيهِ وَكَانَ كَالَّذِي يَأْكُلُ وَلاَ يَشْبَعُ وَالْيَدُ الْعُلْيَا خَيْرٌ مِنَ الْيَدِ السُّفْلَى ‏"‏ ‏.‏ فَقَالَ حَكِيمٌ فَقُلْتُ يَا رَسُولَ اللَّهِ وَالَّذِي بَعَثَكَ بِالْحَقِّ لاَ أَرْزَأُ أَحَدًا بَعْدَكَ شَيْئًا حَتَّى أُفَارِقَ الدُّنْيَا ‏.‏ فَكَانَ أَبُو بَكْرٍ يَدْعُو حَكِيمًا إِلَى الْعَطَاءِ فَيَأْبَى أَنْ يَقْبَلَهُ ثُمَّ إِنَّ عُمَرَ دَعَاهُ لِيُعْطِيَهُ فَأَبَى أَنْ يَقْبَلَ مِنْهُ شَيْئًا فَقَالَ عُمَرُ إِنِّي أُشْهِدُكُمْ يَا مَعْشَرَ الْمُسْلِمِينَ عَلَى حَكِيمٍ أَنِّي أَعْرِضُ عَلَيْهِ حَقَّهُ مِنْ هَذَا الْفَىْءِ فَيَأْبَى أَنْ يَأْخُذَهُ ‏.‏ فَلَمْ يَرْزَأْ حَكِيمٌ أَحَدًا مِنَ النَّاسِ شَيْئًا بَعْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم حَتَّى تُوُفِّيَ ‏.‏ قَالَ هَذَا حَدِيثٌ صَحِيحٌ ‏.‏
