Hilal (the crescent and the lunar month for the law)

هِلال

Hilal in the lexical sense is the moon in a particular state; technically it is the first sighting of the lit part of the moon on the first night. 1 The law made the crescents times for people: the deferred dealings and the rites (the pilgrimage, fasting, the breaking of the fast) and the matters with legal effects, such as the waiting period, the period of nursing and the period of the oath of abstention. 1 2 Jurists hold that only the lawgiver fixes the times of worship, while the times of transactions are agreed by the parties; an unqualified month is taken as a lunar month. 2 3 The size of the crescent is no guide to the start of the month; what counts is the night of sighting. 3

Adhan (the call to prayer: its ruling, wording, conditions, recommended features and the muezzin)

In law, the adhan is announcing the time of an obligatory prayer in set, transmitted words. The jurists differ on its ruling, between a communal obligation and a strongly recommended practice, and on its wording, tarjia, tathwib, the conditions of order, continuity and raised voice, and the qualities of the muezzin: Islam, manhood, sanity and discernment.
