Abu Hurayra said, "We were sitting with the Messenger of Allah,
may Allah bless him and grant him peace, when a man sneezed and praised
Allah. The Messenger of Allah, may Allah bless him and grant him peace,
said to him, 'May Allah have mercy on you.' Then another man sneezed but
the Prophet did not say anything to him. The man, 'Messenger of Allah!
you responded to the other man, but did not say anything to me!' The Prophet
replied, 'He praised Allah and you were silent.'"
