The book Al-Qul al-Mubin in the Biography of the Master of Messengers is considered the best book written about the Prophet's invasions, as it contains an accurate analysis of the Prophet's positions in all the invasions and a clear detail of his leadership, and how it was the rational leadership that can be enlightened by leaders and leaders of all times and eras.

The book discusses many important points on the subject of Tawhid, including the definition of the vow in language and terminology, the ruling of the vow, the definition of Eid and the divisions of the vow, in addition to addressing the disagreement of scholars on the obligation of disbelief in the vow of disobedience and the ruling of sacrificing in a place where it is sacrificed to someone other than Allah.
