"Over all those endowed with knowledge is The All-Knowing." [Yusuf 12:76]
"In the tongue there are two great diseases; the disease of speech, and the disease of silence. If the tongue is saved from one, it will not be saved from the other. For, the one who is silent in regards to justice is a mute Shaitan, and the one who conveys injustice is an articulate Shaitan." [Ibn Al-Qayyim]
Ask Allah for wisdom and seek refuge with him from ignorance
You shall ask for the weal of what can be given [to you]
For in wisdom all virtues are comprised, as ignorance comprises all vices [Arabic Poem]
