Abstract The problem of the Qibla was one of the central issues in the scientific culture of Medieval Islam, and to solve it properly, one needed mathematics and observation. The mathematics consisted of two parts: plane trigonometry (to construct the trigonometric tables) and spherical trigonometry (as the problem belongs to spherical astronomy). Observation and its instruments were needed to find the geographical coordinates of Mecca and the given location; these coordinates (latitude… 

The Third al-Biruni’s Method for The Determination of Qibla Direction from Kitab Tahdid Nihayat al-Amakin with The Implementation Based on Arduino Board MCU, GPS Module, and Digital Compass

TLDR
Al-Biruni’s Third method from the manuscript Kitab Tahdid Nihayat al-Amakin for determining the Qibla direction of a Location computed in Python 2.7 is described.

Determining Qibla Direction using al-Biruni's First Method from Kitab Tahdid Nihayat al-Amakin with The Implementation Based on Board Arduino MCU, GPS Module, and Digital Compass

TLDR
This paper describes the mathematical algorithm for determining Qibla direction using al-Biruni’s (973 – 1050 CE) first method from Kitab Tahdid Nihayat Al-Amakin using Python, and the result shows that the QibLA direction of al- Biruni‘s first method is equal to modern spherical trigonometry method.
