lowliness and fear is an ignorant fool, not a gnostic. The sign of true knowledge is sincerity of will, and a sincere will cuts off all secondary causes and severs all ties of relationship, so that nothing remains except God. Dhu ´l-Nún says: “Sincerity (_ṣidq_) is the sword of God on the earth: it cuts everything that it touches.” Now sincerity regards the Causer, and does not consist in affirmation of secondary causes. To affirm the latter is to destroy the principle of sincerity. Among the stories told of Dhu ´l-Nún I have read that one day he was sailing with his disciples in a boat on the River Nile, as is the custom of the people of Egypt when they desire recreation. Another boat was coming up, filled with merry—makers, whose unseemly behaviour so disgusted the disciples that they begged Dhu ´l-Nún to implore God to sink the boat. Dhu ´l-Nún raised his hands and cried: “O Lord, as Thou hast given these people a pleasant life in this world, give them a pleasant life in the next world too!” The disciples were astonished by his prayer. When the boat came nearer and those in it saw Dhu ´l-Nún, they began to weep and ask pardon, and broke their lutes and repented unto God. Dhu ´l-Nún said to his disciples: “A pleasant life in the next world is repentance in this world. You and they are all satisfied without harm to anyone.” He acted thus from his extreme affection towards the Moslems, following the example of the Apostle, who, notwithstanding the ill-treatment which he received from the infidels, never ceased to say: “O God! direct my people, for they know not.” Dhu ´l-Nún relates that as he was journeying from Jerusalem to Egypt he saw in the distance some one advancing towards him, and felt impelled to ask a question. When the person came near he perceived that it was an old woman carrying a staff (_`ukkáza_[65]), and wearing a woollen tunic (_jubba_). He asked her whence she came. She answered: “From God.” “And whither goest thou?” “To God.” Dhu ´l-Nún drew forth a piece of gold which he had with him and offered it to her, but she shook her hand in his face and cried: “O Dhu ´l-Nún, the notion which thou hast formed of me arises from the feebleness of thy intelligence. I work for God’s sake, and accept nothing unless from Him. I worship Him alone and take from Him alone.” With these words she went on her way. Footnote 65: According to a marginal gloss in I, _`ukkáza_ is a tripod on which a leathern water-bottle is suspended.
