Sahih al-Bukhari, Volume 5, Book 59, Hadith 357 (USC-MSA)

Narrated Qais: The Badr warriors were given five thousand (Dirhams) each, yearly. `Umar said, "I will surely give them more than what I will give to others."

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، سَمِعَ مُحَمَّدَ بْنَ فُضَيْلٍ، عَنْ إِسْمَاعِيلَ، عَنْ قَيْسٍ، كَانَ عَطَاءُ الْبَدْرِيِّينَ خَمْسَةَ آلاَفٍ خَمْسَةَ آلاَفٍ‏.‏ وَقَالَ عُمَرُ لأُفَضِّلَنَّهُمْ عَلَى مَنْ بَعْدَهُمْ‏.‏
