Hishām narrated that Ḥasan said, ‘When a man seeks knowledge, it will very swiftly become apparent in his humility, his sight, his tongue, his hands, his prayer, his speech and his self-discipline. When a man obtains one of the areas of knowledge and he practices it, it will be better for him than the whole of this world and all it contains, if he were to have it and put it in the Next World. (Ibn ʿAbd al-Barr 315).
