Knowledge is Real Wealth
Prophet Muhammad (Pbuh) said: “If anyone travels on a road in search of knowledge, God will ease the way to paradise for him. The angels will lower their wings in their great pleasure with one who seeks knowledge. The inhabitants of the heavens and the Earth and (even) the fish in the deep waters will ask forgiveness for the learned man. The superiority of the knowledgeable man over the worshiper in Islam is like the superiority of the full moon over the rest of the planets. The Prophets did not leave behind wealth, but they left behind knowledge. And whoever takes this knowledge takes a great fortune.”
(Abu Dawud, Ibn Majah, Tirmidhi).
