"The (real) believer is one who will count the proceeds of every affair, his commercial transactions, his food, and his goods in stock, separating one tenth as his dues (mal-i wajibat). Then he, with true faith and perfect affection, with full sincerity, affectionately and lovingly, must deliver that tithe into the presence of the Imam of the time. If he delivers this in pure, true and strong faith, he will see both the affluence in this world and bliss in the hereafter. God the All-High will be pleased by him. When he has delivered the dues to his Lord (Khudawand), — this will serve as the sign and mark of faithfulness (mu'mini), his obedience and religious sincerity (ikhlas-i kishi). Such a person must be patient, sincere, pious, truthful, clean, modest, and humble as a darwish, regarding himself as nothing, and (feeling) sinful from top to toe. He must not be selfish nor proud, nor self-centered, nor egotistic."
