Some Ṣúfís perform obligatory acts of devotion openly, but conceal those which are supererogatory in order that they may escape from ostentation (_riyá_). Anyone (they say) who desires that others should take notice of his religious practices becomes a hypocrite; and if he says that although other people see his devotions he himself is unconscious of them, that too is hypocrisy. Other Ṣúfís, however, exhibit both their obligatory and supererogatory acts of devotion, on the ground that ostentation is unreal and piety real: therefore, it is absurd to hide reality for the sake of unreality. “Do not let any thought of ostentation (they say) enter your heart, and worship God wherever you will.” The Shaykhs have observed the true spirit of the rules of devotional practice, and have enjoined their disciples to do the same. One of them says: “I travelled for forty years, and during that time I did not miss a single public service of prayer, but was in some town every Friday.” The corollaries of prayer belong to the stations of love, of which I will now set forth the principles in full. _Chapter concerning Love and matters connected therewith._ God hath said, “_O believers, whosoever among you apostatize from their religion, God will assuredly bring in their stead a people whom He will love and who will love Him_” (Kor. v, 59); and He hath also said, “_Some men take idols beside God and love them as they love God, but the believers love God best_” (Kor. ii, 160). And the Apostle said: “I heard Gabriel say that God said, ‘Whoever despises any of My friends has declared war against Me. I do not hesitate in anything as I hesitate to seize the soul of My faithful servant who dislikes death and whom I dislike to hurt, but he cannot escape therefrom; and no means whereby My servant seeks My favour is more pleasing to Me than the performance of the obligations which I have laid upon him; and My servant continuously seeks My favour by works of supererogation until I love him, and when I love him I am his hearing and his sight and his hand and his helper.’” And the Apostle also said, “God loves to meet those who love to meet Him, and dislikes to meet those who dislike to meet Him”; and again, “When God loves a man He says to Gabriel, ‘O Gabriel, I love such and such a one, so do thou love him’; then Gabriel loves him and says to the dwellers in Heaven, ‘God loves such and such a one,’ and they love him too; then he bestows on him favour in the earth, so that he is loved by the inhabitants of the earth; and as it happens with regard to love, so does it happen with regard to hate.”
