Prophet Muhammad (may Allah’s peace and blessings be upon him) said that I will recognize my true followers on the Day of Judgement, by their traces of ablution. Islam wants the believer to be pure, and wudhu is the «weapon» that helps us abstain from impurities and anything that is difficult for the feelings, as the same as
