In this book, the author followed a clear approach, making it in two parts: a special section for the Dad Bab, arranged the alphabet, and a special section for the door of Al -Dhaa, arranged the alphabet as well. And he mentioned a portion of the words other than its roots, because it looked at the first letter of it, so the words came: supplication, disturbing, compensation, arresting, and stepping in the chapter of the T, and so on. The author was martyred in the Holy Qur'an in four places, and the noble hadith in three places, proverbs and sayings in three places, and to the common meanings of one word in many places. The book is the first effect published by Abu Bakr Al -Shaibani Al -Mawsali
