It is narrated from Hazrat Aisha (may Allah be pleased with her) that a man sneezed in the gathering of the Prophet (peace and blessings be upon him). He asked, "O Messenger of Allah! What should I say?" The Prophet (peace and blessings be upon him) said: Say "Alhamdulillah." The people asked, "O Messenger of Allah! What should we say?" The Prophet (peace and blessings be upon him) said: Say "Alhamdulillah." The people asked, "O Messenger of Allah! What should we reply to him?" The Prophet (peace and blessings be upon him) said: Say to him "Yarhamuk Allah." The one who sneezed asked, "O Messenger of Allah! What should I reply to them?" The Prophet (peace and blessings be upon him) said: Say to them "Yahdikumullah wa yuslihu balakum."
