Etiquette
Replying to one who sneezes
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنْ عِكْرِمَةَ بْنِ عَمَّارٍ، عَنْ إِيَاسِ بْنِ سَلَمَةَ بْنِ الأَكْوَعِ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يُشَمَّتُ الْعَاطِسُ ثَلاَثًا فَمَا زَادَ فَهُوَ مَزْكُومٌ .
It was narrated from Ilyas bin Salamah bin Akwa' that his father said: "The Messenger of Allah(ﷺ) said: 'The one who sneezes may be responded to three times; if he sneezes more than that, he has a cold.'"
