The qibla compass is a magnetic compass which includes a table or a list of qibla angles from major settlements. Some electronic versions use satellite coordinates to calculate and indicate the qibla automatically. [71] Qibla compasses have existed since around 1300, supplemented by the list of qibla angles often written on the instruments ...
A qibla (qiblah) compass (sometimes also called qibla/qiblah indicator or qiblanuma) is a modified compass used by Muslims to indicate the direction to face to perform prayers. In Islam , this direction is called qibla , and points towards the city of Mecca and specifically to the Kaaba .
The qibla is the direction of the Kaaba, a cube-shaped building at the centre of the Great Mosque of Mecca (al-Masjid al-Haram) in the Hejaz region of Saudi Arabia. [1] This direction is special in Islamic rituals and religious law because Muslims must face it during daily prayers and in other religious contexts. [2]
In Islam, the direction of prayer is known as the qibla and this direction is towards the Sacred Mosque (al-Masjid al-Ḥarām) of Mecca.Originally the qibla of Muhammad and his followers in Medina was towards Jerusalem, but it was changed to Mecca after the Quranic verses (Al-Baqarah 2:144, 2:145) were revealed in the second Hijri year (624 CE), about 15 or 16 months after Muhammad's ...
In navigation, a rhumb line, rhumb (/ r ʌ m /), or loxodrome is an arc crossing all meridians of longitude at the same angle, that is, a path with constant azimuth (bearing as measured relative to true north). Navigation on a fixed course (i.e., steering the vessel to follow a constant cardinal direction) would result in a rhumb-line track.

Late in the 13th century, the Yemeni Sultan and astronomer al-Malik al-Ashraf described the use of the compass as a "Qibla indicator" to find the direction to Mecca. [40] In a treatise about astrolabes and sundials , al-Ashraf includes several paragraphs on the construction of a compass bowl (ṭāsa).
To calculate prayer times two astronomical measures are necessary, the declination of the sun and the difference between clock time and sundial clock. This difference being the result of the eccentricity of the Earth's orbit and the inclination of its axis, it is called the equation of time. The declination of the sun is the angle between sun's ...
