What is the significance of knowing the Beautiful Names of Allah?

Knowing the Most Beautiful Names of Allah is of great importance, because knowledge of them is the noblest and most glorious of all sciences. It leads to loving Him, fearing Him, hoping in Him, and dedicating all actions to Him. It is a path to increasing faith and encompasses all three types of Tawhid (monotheism). Furthermore, Allah created creation so that they may know Him and worship Him, and knowledge of His Most Beautiful Names is the key to the call of the Messengers and the origin of knowledge of everything known.
