The book of the joy of time in the history of Yemen, written by Taj al -Din Abdul Baqi bin Abdul Majeed Al -Yamani, was Al -Nuwairi, who narrated this book for us more than six centuries ago. And it is strange that what Al -Nuwairi said at that time is what is repeated today. Just as Al -Nuwairi had guided to this great book of the Yemeni writer Taj al -Din Abd al -Baqi bin Abdul Majeed al -Yamani, after which he came in our time, a friend of Fadel, Mustafa Hijazi, so he sent us this book, which is missing after he achieved it and commented on it.
