عَن أَنَسِ بْنِ مَالِكٍ رَضِيَ اللهُ عَنهُ قَالَ قَالَ رَسُولُ اللهِ صَلَى اللهُ عَلَيهِ وَسَلَّمَ مَنْ تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ وَعَادَ أَخَاهُ الْمُسْلِمَ مُحْتَسِبًا بُوْعِدَ مِنْ جَهَنَّمَ مَسِيرَةَ سَبْعِينَ خَرِيفًا. (أبو داود ص441)
Hadhrat Anas (Radhiyallahu Anhu) reports that Rasulullah (Sallallahu Alaihi Wasallam) said: “The one who makes a perfect wudhu (i.e. through fulfilling all the sunan and mustahabbaat 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 away from Jahannum the distance of seventy years.
