It is obligatory to purify oneself when water is available

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions. If water is available, it is obligatory to use it in purifying yourselves, whether in performing Wudu’ or Ghusl (ritual bath). However, Tayammum becomes permissible when water is unavailable such as when it is far away or difficult to obtain before the time of Salah (prayer).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
