Assessment of the book (Teaching the Prayer) by al-Suwaf

I have a small booklet titled: Teaching the Prayer, authored by Shaykh Muhammad Mahmud al-Suwaf. I took some supplications from it for the prostration, after the tashahhud, and after the prayer. Is this booklet among the reliable books? Please give us a ruling, may Allah reward you with good.
Answer: I have read part of this book and a summary of it. It is a good and beneficial book, based on what I have seen of it. The Department of Ifta distributes it because its author is known to us for his knowledge, virtue, and sincere advice. So, if Allah wills, it is a beneficial book. For this reason, we distributed it when we learned of its great benefit for men and women. Yes.
