Abu Hurairah (May Allah be pleased with him) reported: I heard Messenger of Allah (PBUH) 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".
[At-Tirmidhi].

Commentary: This Hadith highlights the merit of visiting the sick and Muslim to gain the Pleasure of Allah.
