A Certainty Nothing Can Shake

The Messenger of Allah (peace be upon him) initially was instructed to keep the message…

Yaqīn is a state of conviction where nothing can bring doubts into the heart. So the heart has absorbed īmān to a level where it makes the heart unshakable. That is yaqīn. It is strong to the extent that one would have more faith in what they believe than what they would see or hear. That is a key — it is as if one sees something in front of one's eyes, even though one does not see it. That is the level of yaqīn. It is clear that all of these four had that level of īmān. For example, take the example of Āsiyah, the wife of Pharaoh.
