وَحَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عُبَيْدِ، اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ أَنَّ أَبَا هُرَيْرَةَ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏"‏ لاَ طِيَرَةَ وَخَيْرُهَا الْفَأْلُ ‏"‏ ‏.‏ قِيلَ يَا رَسُولَ اللَّهِ وَمَا الْفَأْلُ قَالَ ‏"‏ الْكَلِمَةُ الصَّالِحَةُ يَسْمَعُهَا أَحَدُكُمْ ‏"‏ ‏.‏
