Introduction
Almighty Allah says in the Holy Quran:
Indeed, Allah conferred a great favor on the believers that He raised amongst them (the most eminent) Messenger (blessings and peace be upon him) from amongst themselves, who recites to them His Revelations, purifies them, and educates them on the Book and Wisdom though, before that, they were in manifest error.
Surah Ale Imran (3:64)
