Mishkat al-Masabih 212

Kathir b. Qais told how, when he was sitting with Abu Darda’ in
the mosque of Damascus, a man came to him and said, “Abu Darda’,
I have come to you from the town of the Messenger for a tradition I have
heard that you relate from God’s messenger. I have come for no other
purpose.” He replied that he had heard God’s messenger say, “ If anyone travels on a road in search of knowledge God will cause him to
travel on one of the roads of paradise, the angels will lower their wings
from good pleasure with one who seeks knowledge, and the inhabitants
of the heavens and the earth and the fish in the depth of the water will
ask forgiveness for him. The superiority of the learned man over the
devout man is like that of the moon on the night when it is full over the
rest of the stars. The learned are the heirs of the prophets who leave
neither dinar nor dirham, leaving only knowledge, and he who accepts it
accepts an abundant portion.” Ahmad, Tirmidhi, Abu Dawud, Ibn Majah
and Darimi transmitted it, Tirmidhi calling Him Qais b. Kathir.
