Wisdom from Prophets

Acquire knowledge, because one who gains it for the sake of Lord, performs an act of piety; who talks about it praises the Lord; who seeks it, adores God; who spends life in light of it, bestows alms; and who passes on it to others, performs an act of devotion to God. Knowledge helps to distinguish what is forbidden from what is not; lights the way to Heaven; it is our friend in the desert, our companion in solitude, when bereft of friends; it guides us to happiness; it sustains us in misery; it is our beauty and grace in the company of friends; it serves as an armor against our enemies. With knowledge, the creation of God rises to the heights of goodness and nobility, controls the affairs of this world and attains the perfection in happiness hereafter

–Prophet Muhammad (PBUH)

Wisdom from Quran

And among His Signs is this, that He created for you mates from among yourselves, that ye may dwell in tranquility with them, and He has put love and mercy between your (hearts): verily in that are Signs for those who reflect (30:21)

Wisdom from Imams

Generosity is to help a deserving person without his request, and if you help him after his request, then it is either out of self-respect or to avoid rebuke. -Imam Ali (a.s.)
