1. It is mustahab to make wudhu before visiting the sick. ^[1]

Hazrat Anas (radhiyallahu ‘anhu) reports that Hazrat Rasulullah (sallallahu ‘alaihi wasallam) said, “The one who makes a perfect wudhu (i.e. through fulfilling all the sunnah and mustahab acts of wudhu) and sets out to visit his sick Muslim brother with the hope of receiving the rewards for visiting the sick, such a person will be kept a distance of seventy years away from Jahannum.” ^[2]
