حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، عَنْ سُلَيْمَانَ التَّيْمِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ عَطَسَ رَجُلاَنِ عِنْدَ النَّبِيِّ ـ صلى الله عليه وسلم ـ فَشَمَّتَ أَحَدَهُمَا - أَوْ سَمَّتَ - وَلَمْ يُشَمِّتِ الآخَرَ فَقِيلَ يَا رَسُولَ اللَّهِ عَطَسَ عِنْدَكَ رَجُلاَنِ فَشَمَّتَّ أَحَدَهُمَا وَلَمْ تُشَمِّتِ الآخَرَ فَقَالَ " إِنَّ هَذَا حَمِدَ اللَّهَ وَإِنَّ هَذَا لَمْ يَحْمَدِ اللَّهَ " .
