Imam Sadiq (a.s) said: Whoever acquires knowledge for God's sake, and practices it and teaches it to others for God's sake will be highly respected in the high ranks of the heavens. About him they will say: he learned for God's sake, practiced for God's sake and taught for God's sake.”
عن أبي عبد الله (عليه السلام): من تعلم وعمل وعلم لله دعي في ملكوت السماوات عظيما، فقيل له: تعلم لله واعمل لله وعلم لله، قال: نعم.
