حَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا حَفْصٌ، - وَهُوَ ابْنُ غِيَاثٍ - عَنْ سُلَيْمَانَ، التَّيْمِيِّ عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ عَطَسَ عِنْدَ النَّبِيِّ صلى الله عليه وسلم رَجُلاَنِ فَشَمَّتَ أَحَدَهُمَا وَلَمْ يُشَمِّتِ الآخَرَ فَقَالَ الَّذِي لَمْ يُشَمِّتْهُ عَطَسَ فُلاَنٌ فَشَمَّتَّهُ وَعَطَسْتُ أَنَا فَلَمْ تُشَمِّتْنِي ‏.‏ قَالَ ‏"‏ إِنَّ هَذَا حَمِدَ اللَّهَ وَإِنَّكَ لَمْ تَحْمَدِ اللَّهَ ‏"‏ ‏.‏

Iyas b. Salama b. al-Akwa reported that his father reported to him that he heard Allah's Apostle (ﷺ) as saying

A person sneezed in his presence and he said to him: May Allah have mercy upon you. And he then sneezed for the second time and Allah's Messenger (ﷺ) said to him: He is suffering from cold (and no response is necessary).
