Visiting the Sick

1.  Feed the hungry, visit the sick and free the captive.
(Bukhari).

2.  When you visit an invalid tell him to make a supplication for you, for his supplication is like of the angels.
(Ibn Majah).

3.  A Muslim has five duties towards another Muslim; to return a salutation, visit the sick, follow funerals, accept an invitation and say, "Allah have mercy on you" when one sneezes.
(Bukhari, Muslim).
