Abu Ad-Darda reported: The Messenger of Allah, peace and blessings be upon him, said:

Whoever travels a path in search of knowledge, then Allah will ease for him the path to Paradise. Verily, the angels lower their wings for the seeker of knowledge. Verily, the inhabitants of the heavens and the earth, even the fish in the depths of the water, will seek forgiveness for the scholar. Verily, the virtue of the scholar over the worshiper is as the superiority of the moon over the stars. Verily, the scholars are the inheritors of the Prophets. They do not leave behind gold or silver coins, but rather they leave behind knowledge. Whoever has taken hold of it has been given an abundant share.
