Sahih Bukhari Volume 2, Book 23, Hadith 1276

حَدَّثَنَا مُحَمَّدُ بْنُ مُقَاتِلٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا شُعْبَةُ، عَنْ سَعْدِ بْنِ إِبْرَاهِيمَ، عَنْ أَبِيهِ، إِبْرَاهِيمَ أَنَّ عَبْدَ الرَّحْمَنِ بْنَ عَوْفٍ ـ رضى الله عنه ـ أُتِيَ بِطَعَامٍ وَكَانَ صَائِمًا فَقَالَ قُتِلَ مُصْعَبُ بْنُ عُمَيْرٍ وَهُوَ خَيْرٌ مِنِّي، كُفِّنَ فِي بُرْدَةٍ، إِنْ غُطِّيَ رَأْسُهُ بَدَتْ رِجْلاَهُ، وَإِنْ غُطِّيَ رِجْلاَهُ بَدَا رَأْسُهُ ـ وَأُرَاهُ قَالَ ـ وَقُتِلَ حَمْزَةُ وَهُوَ خَيْرٌ مِنِّي، ثُمَّ بُسِطَ لَنَا مِنَ الدُّنْيَا مَا بُسِطَ ـ أَوْ قَالَ أُعْطِينَا مِنَ الدُّنْيَا مَا أُعْطِينَا ـ وَقَدْ خَشِينَا أَنْ تَكُونَ حَسَنَاتُنَا عُجِّلَتْ لَنَا، ثُمَّ جَعَلَ يَبْكِي حَتَّى تَرَكَ الطَّعَامَ‏

Narrated By Ibrahim : Once a meal was brought to 'Abdur-Rahman bin 'Auf and he was fasting. He said, "Mustab bin 'Umar was martyred and he was better than I and was shrouded in his Burd and when his head was covered with it, his legs became bare, and when his legs were covered his head got uncovered. Hamza was martyred and was better than I. Now the worldly wealth have been bestowed upon us (or said a similar thing). No doubt, I fear that the rewards of my deeds might have been given earlier in this world." Then he started weeping and left his food.
