Sahih al-Bukhari 2909

Arabic

حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا الأَوْزَاعِيُّ، قَالَ سَمِعْتُ سُلَيْمَانَ بْنَ حَبِيبٍ، قَالَ سَمِعْتُ أَبَا أُمَامَةَ، يَقُولُ لَقَدْ فَتَحَ الْفُتُوحَ قَوْمٌ مَا كَانَتْ حِلْيَةُ سُيُوفِهِمِ الذَّهَبَ وَلاَ الْفِضَّةَ، إِنَّمَا كَانَتْ حِلْيَتُهُمُ الْعَلاَبِيَّ وَالآنُكَ وَالْحَدِيدَ‏.‏
