Also, supplication is a form of worship and recognition of man’s servitude to Allah. The fruits of this pertain to the hereafter. The aims pertaining to this world are the times of a particular sort of supplication and worship. For example, the prayers and supplications for rain are a form of worship. Drought is the time for such worship. Worship and supplications of this sort are not in order to bring rain. If they are performed with that intention alone they are not worthy of acceptance, for they are not sincere worship. Sunset is the time of the evening prayers. And eclipses of the sun and moon are the times of two particular prayers known as salat-i kusuf and sa-lat-i husuf. That is to say, with the veiling of the two luminous signs of the night and day, Allah’s tremendousness is proclaimed, so Almighty Allah calls his servants to a sort of worship at those times. The prayers are not so that the sun and moon will be revealed (whose appearance and how long the eclipses will continue have anyway been reckoned by astronomers).
In just the same way, drought is the time for the prayers for rain. And the visitation of calamities and infliction of harmful things the times of certain supplications when man realizes his impotence and through his supplication and entreaty seeks refuge at the Court of One Possessing Absolute Power.
