4-101 Ja’far ibn Ali ibn al-Hassan ibn al-Kufy - may God be pleased with him - narrated that his grandfather Al-Hassan ibn Ali quoted on the authority of his great grandfather Abdullah ibn al-Muqayrih, on the authority of Al-Sakoony, on the authority of Ja’far ibn Muhammad as-Sadiq (MGB), on the authority of his father (MGB), “Knowledge is a treasure, the key for which is asking. Therefore ask, may God have Mercy upon you. Four people shall benefit from knowledge: those who ask questions; those who respond to the questions; those who listen to them; and those who like the above three.”
