Narrated Abu 'Is-haq: Al-Bara' was asked, "Was the face of the Prophet (as bright) as a sword?" He said, "No, but (as bright) as a moon."
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا زُهَيْرٌ، عَنْ أَبِي إِسْحَاقَ، قَالَ سُئِلَ الْبَرَاءُ أَكَانَ وَجْهُ النَّبِيِّ صلى الله عليه وسلم مِثْلَ السَّيْفِ قَالَ لاَ بَلْ مِثْلَ الْقَمَرِ.
