Mubárak said: “Tranquillity is unlawful to the hearts of the Saints of God,” for they are agitated in this world by seeking God (_ṭalab_) and in the next world by rapture (_ṭarab_); they are not permitted to rest here, while they are absent from God, nor there, while they enjoy the presence, manifestation, and vision of God. Hence this world is even as the next world in their eyes, and the next world even as this world, because tranquillity of heart demands two things, either attainment of one’s aim or indifference to the object of one’s desire. Since He is not to be attained in this world or the next, the heart can never have rest from the palpitation of love; and since indifference is unlawful to those who love Him, the heart can never have rest from the agitations of seeking Him. This is a firm principle in the path of spiritual adepts. 8. ABÚ `ALÍ AL-FUḌAYL B. `IYÁḌ. He is one of the paupers (_ṣa`álík_) of the Ṣúfís, and one of their most eminent and celebrated men. At first he used to practise brigandage between Merv and Báward, but he was always inclined to piety, and invariably showed a generous and magnanimous disposition, so that he would not attack a caravan in which there was any woman, or take the property of anyone whose stock was small; and he let the travellers keep a portion of their property, according to the means of each.

When they reached the place where Fuḍayl was lying in ambush, the reader happened to be reciting: “_Is not the time yet come unto those who believe, that their hearts should humbly submit to the admonition of God?_” (Kor. lvii, 15). Fuḍayl’s heart was softened. He repented of the business in which he was engaged, and having a written list of those whom he had robbed he satisfied all their claims upon him. Then he went to Mecca and resided there for some time and became acquainted with certain saints of God. Afterwards he returned to Kúfa, where he associated with Abú Ḥanífa. He has handed down relations which are held in high esteem by Traditionists, and he is the author of lofty sayings concerning the verities of Ṣúfiism and Divine Knowledge. It is recorded that he said: “Whoever knows God as He ought to be known worships Him with all his might,” because everyone who knows God acknowledges His bounty and beneficence and mercy, and therefore loves Him; and since he loves Him he obeys Him so far as he has the power, for it is not difficult to obey those whom one loves. Accordingly, the more one loves, the more one is obedient, and love is increased by true knowledge.[62] It is related that he said: “The world is a madhouse, and
