Note 33 — The Second Book.
Reading edition
The Arabians divide their day into twenty four hours, and reckon them from one setting sun to another. As very few among them know what a watch is, and as they conceive, but imperfectly the duration of an hour, they usually determine time almost as when we say, it happened about noon, about evening, &c. The moment when the Sun disappears is called Maggrib, about two hours afterwards they call it El ascha; two hours later, El märfa; midnight Nus el lejl: the dawn of morning El fadsjer: sun rise Es subhh. They eat about nine in the morning, and that meal is called El ghadda; noon El duhhr; three hours after noon El asr. Of all these divisions of time only noon and midnight are well ascertained; they both fall upon the twelfth hour. The others are earlier or later as the days are short or long. The five hours appointed for prayer are Maggrib, Nus el lejl, El fedsjer, Duhhr, and El asr.
