(9) باب تَشْمِيتِ الْعَاطِسِ وَكَرَاهَةِ التَّثَاؤُبِ
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). (ID)
