The most honorable and useful knowledge is knowledge of God, and this knowledge of God can be acquired only through the verses of the Holy Quran and the hadiths (narrations) of Ahl al-Bayt (AS).
One day, on the pulpit, the Holy Prophet (PBUH&HP) said to the people: whoever wants to see Adam with his science, Noah with his resolution, Ibrahim with his patience, Moses with his grandeur and awe and Jesus with his asceticism, then look at Ali ibn Abi Talib (peace be upon him)- namely, this one person is alone all the divine prophets.
