Two men sneezed in the presence of the prophet (May peace be upon him). He said : Allah have mercy on you! To one and not to the other. He was asked: Messenger of Allah! Two persons sneezed. Ahmad’s version has: You invoked a blessing on one of them and left the other. He replied : This man praised Allah, and this man did not praise Allah. (Using translation from Abū Dāʾūd 5039)
عَطَسَ رَجُلَانِ عِنْدَ النَّبِيِّ ﷺ فَشَمَّتَ أَحَدَهُمَا أَوْ قَالَ فسَمَّتَ أَحَدَهُمَا وَتَرَكَ الْآخَرَ فَقِيلَ هُمَا رَجُلَانِ عَطَسَا فَشَمَّتَّ أَوْ قَالَ فَسَمَّتَّ أَحَدَهُمَا وَتَرَكْتَ الْآخَرَ فَقَالَ إِنَّ هَذَا حَمِدَ اللهَ وَإِنَّ هَذَا لَمْ يَحْمَدِ اللهَ قَالَ سُلَيْمَانُ أُرَاهُ نَحْوًا مِنْ هَذَا
