Imam al-Kazim (as): Comprehend and understand the religion of Allah, for jurisprudence is the key to vision and the completion of worship and the cause of reaching the lofty grades and magnanimous stations in the world and here after. And the superiority and magnanimity of jurisprudent over the adorer and worshiper is like that of the superiority of sun to the stars. And Allah does not get pleased with (accept) any practice of that person who does not achieve the comprehension and understanding of his religion. Tuḥaf al-‘Uqūl
