Hazrat Shaqiq (may Allah have mercy on him) narrates that Hazrat Abdullah bin Masood (may Allah be pleased with him) said: If the knowledge of all the living people of Arabia were placed on one side of the scale and the knowledge of Hazrat Umar (may Allah be pleased with him) were placed on the other side, the knowledge of Hazrat Umar (may Allah be pleased with him) would outweigh them all.
