Fear of searching for evidence to look into it to lead to knowledge of the meaning. Ignorance of the essence of the evidence that it is evidence. One of two things must be done. Either he imitates someone in that this is evidence of a matter assigned to him, or he lacks consideration and thought about what he should take. As evidence of knowing God, if it is the first, then he should remain in his imitation of knowing God, and he is the one who is called tayammum. And whoever says that it is not permissible for him to do tayammum, he says that this fear does not oblige him not to look, so let him look, and it is necessary.
