After faith, the first thing incumbent on everyone is purification (_ṭahárat_) and the performance of prayer, i.e. to cleanse the body from filth and pollution, and to wash the three members,[146] and to wipe the head with water as the law prescribes, or to use sand in the absence of water or in severe illness. Purification is of two kinds: outward and inward. Thus prayer requires purification of the body, and gnosis requires purification of the heart. As, in the former case, the water must be clean, so in the latter case unification must be pure and belief undefiled. The Ṣúfís are always engaged in purification outwardly and in unification inwardly. The Apostle said to one of his Companions: “Be constant in ablution, that thy two guardian angels may love thee,” and God hath said: “_God loves those who often repent and those who purify themselves_” (Kor. ii, 222). And the Apostle used to say in his invocations: “O God, purify my heart from hypocrisy.” Even consciousness of the miraculous grace (_karámát_) vouchsafed to him he regarded as an affirmation of other than God, for in unification it is hypocrisy (_nifáq_) to affirm other than God. So long as a disciple’s eye is obscured by a single atom of the miracles of the Shaykhs, from the standpoint of perfection that atom is a potential veil (between him and God). Hence Abú Yazíd said: “The hypocrisy of gnostics is better than the sincerity of disciples,” i.e. that which is a “station” (_maqám_) to the novice is a veil to the adept. The novice desires to gain miracles, but the adept desires to gain the Giver of miracles. In short, the affirmation of miracles, or of anything that involves the sight of other than God, appears hypocrisy to the people of the Truth (the Ṣúfís). Accordingly, what is noxious to the friends of God is a means of deliverance for all sinners, and what is noxious to sinners is a means of salvation for all infidels, because, if infidels knew, as sinners know, that their sins are displeasing to God, they would all be saved from infidelity; and if sinners knew, as the friends of God know, that all their actions are defective, they would all be saved from sin and purged of contamination. Therefore, outward and inward purification must go together; e.g., when a man washes his hands he must wash his heart clean of worldliness, and when he puts water in his mouth he must purify his mouth from the mention of other than God, and when he washes his face he must turn away from all familiar objects and turn towards God, and when he wipes his head he must resign his affairs to God, and when he washes his feet he must not form the intention of taking his stand on anything except according to the command of God. Thus he will be doubly purified. In all religious ordinances the external is combined with the internal; e.g. in faith, the tongue’s profession with the heart’s belief. The method of spiritual purification is to reflect and meditate
