Sahih Bukhari Volume 2, Book 24, Hadith 1473

وَحَدَّثَنَا عَبْدَانُ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا يُونُسُ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، وَسَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّ حَكِيمَ بْنَ حِزَامٍ ـ رضى الله عنه ـ 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 كَالَّذِي يَأْكُلُ وَلاَ يَشْبَعُ، الْيَدُ الْعُلْيَا خَيْرٌ مِنَ الْيَدِ السُّفْلَى ‏"‏‏.‏ قَالَ حَكِيمٌ فَقُلْتُ يَا رَسُولَ اللَّهِ وَالَّذِي بَعَثَكَ بِالْحَقِّ لاَ أَرْزَأُ أَحَدًا بَعْدَكَ شَيْئًا حَتَّى أُفَارِقَ الدُّنْيَا، فَكَانَ أَبُو بَكْرٍ ـ رضى الله عنه ـ يَدْعُو حَكِيمًا إِلَى الْعَطَاءِ فَيَأْبَى أَنْ يَقْبَلَهُ مِنْهُ، ثُمَّ إِنَّ عُمَرَ ـ رضى الله عنه ـ 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 بَعْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم حَتَّى تُوُفِّيَ‏

Narrated By 'Urwa bin Az-Zubair and Said bin Al-Musaiyab : Haklm bin Hizam said, "(Once) I asked Allah's Apostle (for something) and he gave it to me. Again I asked and he gave (it to me). Again I asked and he gave (it to me). And then he said, "O Hakim! This property is like a sweet fresh fruit; whoever takes it without greediness, he is blessed in it, and whoever takes it with greediness, he is not blessed in it, and he is like a person who eats but is never satisfied; and the upper (giving) hand is better than the lower (receiving) hand." Hakim added, "I said to Allah's Apostle , 'By Him (Allah) Who sent you with the Truth, I shall never accept anything from anybody after you, till I leave this world.' " Then Abu Bakr (during his caliphate) called Hakim to give him his share from the war booty (like the other companions of the Prophet), he refused to accept anything. Then 'Umar (during his caliphate) called him to give him his share but he refused. On that 'Umar said, "O Muslims! I would like you to witness that I offered Hakim his share from this booty and he refused to take it." So Hakim never took anything from anybody after the Prophet till he died.
