The Kashf al-mahjúb: The oldest Persian treatise on Súfiism

He was perfectly grounded in the true theory of hope in God, so that Ḥuṣrí says: “God had two Yaḥyás, one a prophet and the other a saint. Yaḥyá b. Zakariyyá trod the path of fear so that all pretenders were filled with fear and despaired of their salvation, while Yaḥyá b. Mu`ádh trod the path of hope so that he tied the hands of all pretenders to hope.” They said to Ḥuṣrí: “The state of Yaḥyá b. Zakariyyá is well known, but what was the state of Yaḥyá b. Mu`ádh?” He replied: “I have been told that he was never in the state of ignorance (jáhiliyyat) and never committed any of the greater sins (kabíra).” In the practice of devotion he showed an intense perseverance which was beyond the power of anyone else. One of his disciples said to him: “O Shaykh, thy station is the station of hope, but thy practice is the practice of those who fear.” Yaḥyá answered: “Know, my son, that to abandon the service of God is to go astray.” Fear and hope are the two pillars of faith. It is impossible that anyone should fall into error through practising either of them. Those who fear engage in devotion through fear of separation (from God), and those who hope engage in it through hope of union (with God). Without devotion neither fear nor hope can be truly felt, but when devotion is there this fear and hope are altogether metaphorical; and metaphors (`ibárat) are useless where devotion (`ibádat) is required. Yaḥyá is the author of many books, fine sayings, and original precepts. He was the first of the Shaykhs of this sect, after the Orthodox Caliphs, to mount the pulpit.

I am very fond of his sayings, which are delicately moulded and pleasant to the ear and subtle in substance and profitable in devotion. It is related that he said: “This world is an abode of troubles (ashghál) and the next world is an abode of terrors (ahwál), and Man never ceases to be amidst troubles or terrors until he finds rest either in Paradise or in Hell-fire.” Happy the soul that has escaped from troubles and is secure from terrors, and has detached its thoughts from both worlds, and has attained to God! Yaḥyá held the doctrine that wealth is superior to poverty. Having contracted many debts at Rayy, he set out for Khurásán. When he arrived at Balkh the people of that city detained him for some time in order that he might discourse to them, and they gave him a hundred thousand dirhems. On his way back to Rayy he was attacked by brigands, who seized the whole sum. He came in a destitute condition to Níshápúr, where he died. He was always honoured and held in respect by the people.
