Chapter on Description of Tayammum, Its Rules for Those in a State of Impurity, and What They Should Observe About Istibra and Istizhar

Then, the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, said: "If the one in a state of Janabah (ritual impurity due to major defilement) intends to purify himself, he first ensures cleanliness as previously explained, and then strikes the ground with the palms of his hands once. With them, he wipes his face, from the hairline to the tip of his nose. He then strikes the ground a second time and wipes the back of his right hand with his left hand and the back of his left hand with his right hand. Thus, the state of Janabah is removed, and prayer becomes permissible for him."
