Knowledge

Do not follow what you have no knowledge of. Surely, hearing, sight, and heart, each will be questioned.

17:36(O man), follow not that whereof thou hast no knowledge. Lo! the hearing and the sight and the heart - of each of these it will be asked.

And so those gifted with knowledge may know it is the truth from your Lord, and thus believe in it humbly.

22:54And that those who have been given knowledge may know that it is the truth from thy Lord, so that they may believe therein and their hearts may submit humbly unto Him. Lo! Allah verily is guiding those who believe unto a right path.
