It has been narrated from Jaabir radiyAllaahu `anh that the Messenger of Allaah sallallaahu `alayhi wasallam said: “Whoever visited a sick person does not cease to swim in mercy until he returns home, if he was to sit down he would be immersed in it. ” (Musnad of Imaam Ahmad)
“There is not a Muslim that visits another in the morning except that 70,000 angels ask forgiveness for him until the night, and if he visits him at night then 70,000 angels ask forgiveness for him until the morning, and he will have earned a garden in Paradise.” (at-Tirmidhi)
Allaah will say on the Day of Judgment: “O son of Adam I was sick and you did not visit Me. He will say: O Lord how can I visit You. You are the Lord of the worlds? He says: Did you not know that My servant so and so was sick yet you did not visit him? Did you not know that if you had visited him you would have found Me with him?” (Hadeeth Qudsi – Saheeh Muslim).
“…you would have found Me with him”, subhaan’Allaah this hadeeth never ceases to amaze me every single time I read it. This is coming directly from the Lord of the Universe and what could possibly be more beloved to us than the nearness of Allaah?
