When someone sneezes several times Al-Adab Al-Mufrad 939
Arabic hadith text
حَدَّثَنَا قُتَيْبَةُ، قَالَ: حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ عَجْلاَنَ، عَنِ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ قَالَ: شَمِّتْهُ وَاحِدَةً وَثِنْتَيْنِ وَثَلاَثًا، فَمَا كَانَ بَعْدَ هَذَا فَهُوَ زُكَامٌ.
Translation
Abu Hurayra said, "Wish mercy on a person once, twice and three times. Anything more than that is a cold."
