It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: Two men sneezed in the presence of the Prophet (peace and blessings be upon him), one of whom was of higher standing than the other. The man of higher standing sneezed and did not praise Allah Almighty, so the Prophet (peace and blessings be upon him) did not respond to him. The other man sneezed and praised Allah Almighty, so the Prophet (peace and blessings be upon him) responded to him (i.e. made the prayer in reply). The man of higher standing said: "I sneezed in your presence and you did not respond to me, but this man sneezed in your presence and you responded to him." The Prophet (peace and blessings be upon him) said: "This man remembered Allah, so I remembered him; and you forgot (to remember) Allah Almighty, so I also forgot you (i.e. I left you to your own state)."
Ahmad, and al-Tabarani in al-Mu'jam al-Awsat, recorded it. Ahmad's narrators are the narrators of the Sahih, except Rib'i bin Ibrahim, who is thiqah (trustworthy) and reliable.
