Sahih al-Bukhari, Volume 2, Book 23, Hadith 364 (USC-MSA) ⓘ

Narrated Sa`d from his father: Once the meal of `Abdur-Rahman bin `Auf was brought in front of him, and he said, "Mus`ab bin `Umair was martyred and he was better than I, and he had nothing except his Burd (a black square narrow dress) to be shrouded in. Hamza or another person was martyred and he was also better than I and he had nothing to be shrouded in except his Burd. No doubt, I fear that the rewards of my deeds might have been given early in this world." Then he started weeping.

حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ الْمَكِّيُّ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنْ سَعْدٍ، عَنْ أَبِيهِ، قَالَ أُتِيَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ ـ رضى الله عنه ـ يَوْمًا بِطَعَامِهِ فَقَالَ قُتِلَ مُصْعَبُ بْنُ عُمَيْرٍ ـ وَكَانَ خَيْرًا مِنِّي ـ فَلَمْ يُوجَدْ لَهُ مَا يُكَفَّنُ فِيهِ إِلاَّ بُرْدَةٌ، وَقُتِلَ حَمْزَةُ أَوْ رَجُلٌ آخَرُ خَيْرٌ مِنِّي فَلَمْ يُوجَدْ لَهُ مَا يُكَفَّنُ فِيهِ إِلاَّ بُرْدَةٌ، لَقَدْ خَشِيتُ أَنْ يَكُونَ قَدْ عُجِّلَتْ لَنَا طَيِّبَاتُنَا فِي حَيَاتِنَا الدُّنْيَا، ثُمَّ جَعَلَ يَبْكِي‏.‏
