lbne-Umar Radiyallahu 'anhuma narrates that Rasullullah Sallallahu 'alaihi wasallam said: For a person who performs Wudu (while already) in a state of purity, for him ten virtues are written. (Abu Dawud: 62)
Note: Islamic scholars have written that condition for making fresh
Wudu, while already in a state of Wudu, is that one has performed any
form of worship with the previous Wudu. (Badhl-ul-Majhud)
