Abu Hurairah RA reported: I heard Messenger of
Allah (sallallaahu ’alayhi wa sallam) saying,
"Whosoever visits an ailing person or a brother of
his to seek the Pleasure of Allah, an announcer
(angel) calls out: 'May you be happy, may your
walking be blessed, and may you be awarded a
dignified position in Jannah.'" (Tirmidhi)
