The daily obligatory prayers are three in number. The shortest one consists of a single verse which has to be recited once every twenty-four hours and at mid-day. The medium which begins with the words "The Lord is witness that there is none other God but He" has to be recited three times a day, in the morning, at noon and in the evening. This prayer is accompanied by certain physical acts and gestures. The long prayer, which is the most elaborate of the three, has to be recited only once in every twenty-four hours, and at any time one feels inclined to do so.
The believer is entirely free to choose any one of these three prayers, but is under the obligation of reciting either one of them, and in accordance with any specific directions with which they may be accompanied.
