ومن لم يجد الماء فليتيمم كما قال الله عزوجل: (فتيمموا صعيدا طيبا) والصعيد: الموضع المرتفع، والطيب: الذي ينحدر عنه الماء، فإذا أراد الرجل أن يتيمم ضرب بيديه على الارض مرة واحدة، ثم ينفضهما فيمسح بهما وجهه، ثم يضرب بيده اليسرى الارض فيمسح بها يده اليمنى من المرفق إلى أطراف الاصابع، ثم يضرب بيمينه الارض فيمسح بها يساره من المرفق إلى أطراف الاصابع. وقد روي أن يمسح الرجل جبينه وحاجبيه، ويمسح على ظهر كفيه، وعليه مضى مشايخنا (رضي الله عنهم).
Someone who does not find water is to do tayammum as Allah said, “So betake to wholesome earth” (4:43). “Earth” (sa’eed) means the elevated place; and “wholesome” (tayyib) means that from which the water descends. So, when the man wants to do tayammum, he strikes his hands upon the ground one time, then he shakes them off and wipes his face with them, then he strikes his left hand upon the ground and wipes his right hand with it from the elbow to the ends of the fingers, then he strikes his right hand upon the ground and wipes his left hand with it from the elbow to the tips of the fingers. It has been narrated that the man wipes his forehead and his eyebrows, and wipes upon the back of his hands, and [this is how] our elders  have performed it.
