Al-A'ala ibn Kamil narrated that once he told Imam Musa ibn Ja'far (a.s) that God had granted him so many blessings that he could not even count, and he did not know the reason for that. The Imam (a.s) asked if he really did not know the reason and told him that it was due to his thanksgiving. And in another tradition we read that the
Imam (a.s) told him not to underestimate thanksgiving.”
