Sayyiduna Abu Huraira (may Allah be pleased with him) narrated: We were sitting with the Messenger of Allah (peace and blessings be upon him) when a man sneezed and said: «الحمدللہ», so the Messenger of Allah (peace and blessings be upon him) said: «يرحمك الله». Then another man sneezed, but the Prophet (peace and blessings be upon him) did not say anything to him. So he said: O Messenger of Allah! You responded to that man, but you did not say anything to me. The Prophet (peace and blessings be upon him) said to him: "He praised Allah, whereas you remained silent."
