Q. Sometimes, it becomes unbearable for me to make Wudhu using water. At those times, if I make Wudhu using water, my skin becomes extremely dry and it bleeds. My doctor advised me that if I use water in Wudhu, my condition will become even more worse. What do I do in the case of Wudhu if I can’t use water?
A. In the enquired situation, if a reliable Muslim doctor has confirmed that the use of water in making Wudhu is detrimental to your health, then it would be permissible for you to make Tayammum. (Shaami 1/233)
The necessary method of Tayammum is firstly; to make intention of Tayammum for Wudhu. Secondly, to strike both hands on earth (sand, stone etc.) and rub them on the face. Thirdly, to strike both hands on earth (sand, stone etc.) and rub both arms from the fingertips to and including the elbows.
