895. Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (PBUH) said, "Every Muslim has five rights over another Muslim (i.e., he has to perform five duties for another Muslim): to return the greetings, to visit the sick, to accompany funeral processions, to accept an invitation, to respond to the sneezer [i.e., to say: `Yarhamuk-Allah (may Allah bestow His Mercy on you),' when the sneezer praises Allah].''

So he embraced Islam and the Prophet ?ped out saying, "Praise be to Allah Who has saved him from Hell-fire.''
