Height is the elevation of the highest place of a location above its lowest place.Information about Tamkin is given in the tenth chapter, Prayer Times, of this book.Muhammad bin Mûsâ Baghdâdî and Abû Bakr Muhammad bin ’Umar Munajjim Baghdâdî explained how to determine the time by using the Rub’-i dâira [quadrant] in their books al- ’Amal-u bi-l-usturlâb. The former passed away in 205, and the latter in 320 [A.D. 932]. Another valuable source is the book Rubu’i muqantarât by Abdullah bin Alî Mardînî. He passed away in 779 [A.D. 1377].

Captain Mustafâ Hilmi Efendi, a teacher of fann-i hey’et (astronomy) in the Mekteb-ibahriya-i-shâhâna (Royal Naval Academy), gave perfect calculations of prayer times and of the beginnings of Arabic months in his book Hey’et-i felekiyye, printed in 1306 [A.D. 1888].
