"So whoever renounces false gods and believes in Allah has certainly grasped the firmest, unfailing hand-hold. And Allah is All-Hearing, All-Knowing." [Quran 2:256]

The more that we know about our Prophet ﷺ, the greater our certitude will be in him and in the religion that was revealed to him. We see this manifested in Abu Bakr's response (may Allah be well pleased with him) after the Prophet ﷺ returned from the Night Journey and Heavenly Ascension.
