Hazrat Abu Huraira reported God's messenger Prophet Muhammad PBUH as saying ,
There are six good qualities which one believer should display
to another : he should visit him when he is ill,
be present when he dies,
accept his invitation when he gives one,
salute him when he meets him,
Allah have mercy on you ' when he
sneezes , and act sincerely towards him whether he is absent or present.
These lines have been narrated from The book of hadees Mishkat Shareef ,
and it is a true hadees of Prophet Muhammad PBUH.
