Jami` at-Tirmidhi 3675
Narrated Zaid bin Aslam:
"I heard 'Umar bin Al-Khattab saying: 'We were ordered by the Messenger of Allah (ﷺ) to give in charity, and that coincided with a time in which I had some wealth, so I said, "Today I will beat Abu Bakr, if ever I beat him."' So I came with half of my wealth, and the Messenger of Allah (ﷺ) said: "What did you leave for your family?" I said: "The like of it." And Abu Bakr came with everything he had, so he said: "O Abu Bakr! What did you leave for your family?" He said: "I left Allah and His Messenger for them." I said: '[By Allah] I will never be able to beat him to something.'"
حَدَّثَنَا هَارُونُ بْنُ عَبْدِ اللَّهِ الْبَزَّازُ الْبَغْدَادِيُّ، قَالَ حَدَّثَنَا الْفَضْلُ بْنُ دُكَيْنٍ، قَالَ حَدَّثَنَا هِشَامُ بْنُ سَعْدٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ، يَقُولُ أَمَرَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ نَتَصَدَّقَ فَوَافَقَ ذَلِكَ عِنْدِي مَالاً فَقُلْتُ الْيَوْمَ أَسْبِقُ أَبَا بَكْرٍ إِنْ سَبَقْتُهُ يَوْمًا قَالَ فَجِئْتُ بِنِصْفِ مَالِي فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَا أَبْقَيْتَ لأَهْلِكَ ‏"‏ ‏.‏ قُلْتُ مِثْلَهُ وَأَتَى أَبُو بَكْرٍ بِكُلِّ مَا عِنْدَهُ فَقَالَ ‏"‏ يَا أَبَا بَكْرٍ مَا أَبْقَيْتَ لأَهْلِكَ ‏"‏ ‏.‏ قَالَ أَبْقَيْتُ لَهُمُ اللَّهَ وَرَسُولَهُ قُلْتُ وَاللَّهِ لاَ أَسْبِقُهُ إِلَى شَيْءٍ أَبَدًا ‏.‏ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
