Narrated Anas bin Malik:
that two men sneezed in the presence of the Prophet (ﷺ); he responded to one of them and did not respond to the other. The one who was not responded to said: "O Messenger of Allah! You responded to this person and did not respond to me?' So the Messenger of Allah (ﷺ) said: "He praised Allah while you did not praise Him." (JA)
