The principal Ritual and Moral Laws are on the following subjects, of which the first four are the most important.
Prayer (eṣ-ṣaláh, commonly pronounced eṣ-ṣalah), including preparatory purifications. There are partial or total washings to be performed on particular occasions which need not be mentioned. The ablution which is more especially preparatory to prayer (and which is called wuḍoó) consists in washing the hands, mouth, nostrils, face, arms (as high as the elbow, the right first), each three times; and then the upper part of the head, the beard, ears, neck, and feet, each once. This is done with running water, or from a very large tank, or from a lake, or the sea.--Prayers are required to be performed five times in the course of every day; between daybreak and sunrise, between noon and the 'aṣr (which latter period is about mid-time between noon and nightfall), between the 'aṣr and sunset, between sunset and the 'eshè (or the period when the darkness of night commences), and at, or after, the 'eshè. The commencement of each of these periods is announced by a chant (called adán), repeated by a crier (muëddin) from the mád'neh, or menaret, of each mosque; and it is more meritorious to commence the prayer then than at a later time. On each of these occasions, the Muslim has to perform certain prayers held to be ordained by God, and others ordained by the Prophet; each kind consisting of two, three, or four "rek'ahs;" which term signifies the repetition of a set form of words, chiefly from the Ḳur-án, and ejaculations of "God is most Great!" &c., accompanied by particular postures; part of the words being repeated in an erect posture; part, sitting; and part, in other postures: an inclination of the head and body, followed by two prostrations, distinguishing each rek'ah. These prayers may in some cases be abridged, and in others entirely omitted. Other prayers must be performed on particular occasions. 1. On Friday, the Mohammadan Sabbath. These are congregational prayers, and are similar to those of other days, with additional prayers and exhortations by a minister, who is called Imám, or Khaṭeeb. 2. On two grand annual festivals. 3. On the nights of Ramaḍán, the month of abstinence. 4. On the occasion of an eclipse of the sun or moon. 5. For rain. 6. Previously to the commencement of battle. 7. In pilgrimage. 8. At funerals.
Alms-giving. An alms, called "zekáh," commonly pronounced "zekah," is required by law to be given annually, to the poor, of camels, oxen (bulls and cows), and buffaloes, sheep and goats, horses and mules and asses, and gold and silver (whether in money or in vessels, ornaments, &c.), provided the property be of a certain amount, as five camels, thirty oxen, forty sheep, five horses, two hundred dirhems, or twenty deenárs. The proportion is generally one-fortieth, which is to be paid in kind, or in money, or other equivalent.
Fasting (eṣ-ṣiyám). The Muslim must abstain from eating and drinking, and from every indulgence of the senses, every day during the month of Ramaḍán, from the first appearance of daybreak until sunset, unless physically incapacitated.--On the first day of the following month, a festival, called the Minor Festival, is observed with public prayer, and with general rejoicing, which continues three days.
