It also guides a beginner towards understanding the necessary, impossible, and possible attributes of Allah. In knowing so, a Muslim will be able to properly comprehend the meanings that underlie the first portion of the testimony of faith, which is: There is no god worthy of worship except Allah. To complete it, he will have to affirm the prophethood of Muhammad ﷺ by knowing the necessary, impossible, and possible attributes in regard to him and the other prophets and messengers. Having this book will provide the student the necessary knowledge and certainty in affirming the aforementioned.
