Tawhid of Divinity (Worship)

A book in Italian briefly clarifies the concept of god from the Islamic perspective based on Quranic verses. It also relates some verses from other religions' books about the monotheism doctrine through referring to one god not more but these verses are within a pile of distorted tenets, which confirms that the monotheism doctrine is the faith of all messengers and prophets and all current religions still have this noble belief in their core.
