What does the introduction to the principles of Islam include?

The Hadith of Gabriel included a definition of the principles of Islam. Religion was divided into three ranks:

1. Islam: Includes practical obligations such as: bearing witness that there is no god but Allah and that Muhammad is His Messenger, establishing prayer, giving zakat, fasting Ramadan, and performing the pilgrimage to the House for whoever is able to find a way there. 2. Iman (Faith): Includes the fundamentals of belief, which are: belief in Allah (His existence, Lordship, Divinity, Names and Attributes), belief in the angels, belief in the Books (especially the Quran as it abrogates and is the final one), belief in the Messengers (especially Muhammad, peace be upon him, as he is the final and best of them), belief in the Last Day and what follows it, and belief in divine decree (Allah’s knowledge, His writing, His will, and His creation). 3. Ihsan (Excellence): The highest rank, meaning that you worship Allah as if you see Him, and if you do not see Him, then know that He sees you.

Islam has indeed brought every virtue and fought every vice, and it has brought justice and fairness among people.
