Visiting the sick
مَنْ عَادَ مَرِيضًا لَمْ يَزَلْ فِي خُرْفَةِ الْجَنَّةِ حَتَّى يَرْجِعَ
Man 'ada maridan lam yazal fi khurfati-l-jannati hatta yarji'.
"Whoever visits a sick person remains in the harvest of Paradise until he returns."
Narrated by Thawban. Sahih Muslim 2568
A short reflection
A walk to a hospital bed isn't just kindness, the hadith puts you in the fruits of paradise while you're on your way.
