As salaam alekum ( Peace be upon you)
Hadeeth means the words, actions, approval or attributes that have been narrated from the Messenger (peace and blessings of Allaah be upon him).
Narrated Muawiya bin Suwald:
I heard Al-Bara' bin 'Azib saying, "The Prophet (S.A.W) orders us to do seven things and prohibited us from doing seven other things." Then Al-Bara' mentioned the following:--
(1) To pay a visit to the sick (inquiring about his health),
(2) to follow funeral processions,
(3) to say to a sneezer, "May Allah be merciful to you" (if he says, "Praise be to Allah!"),
(4) to return greetings,
(5) to help the oppressed,
(6) to accept invitations,
(7) to help others to fulfill their oaths.
