What is the qibla?
The qibla is the direction of the Kaaba in Mecca, which Muslims face during the five daily prayers. It is a requirement of prayer for anyone able to determine it. The Kaaba stands at 21.4225° N, 39.8262° E. The obligation is to face the Kaaba's direction, not to see it — those far away face the bearing that points toward it.
How do I find the qibla direction?
Determine true north, then rotate clockwise by your location's qibla bearing. A smartphone qibla compass does both steps at once by reading your GPS position and the device magnetometer. Without a phone you can use a magnetic compass corrected for declination, the position of the sun, or simply align with a nearby mosque's mihrab.
Why is the qibla not simply 'southeast toward Saudi Arabia'?
Because the Earth is a sphere. The shortest path between two points on a sphere is a great circle, and its initial bearing is often surprising. From North America the great-circle route to Mecca runs northeast, not southeast — which is why maps drawn on flat projections mislead people. Qibla calculators solve the spherical triangle rather than drawing a straight line on a flat map.
What is the difference between magnetic north and true north?
A magnetic compass points to the magnetic north pole, which does not coincide with the geographic (true) north pole and drifts over time. The angular gap between them is called magnetic declination and it varies by location — roughly 5-7° east across Türkiye, but over 15° in parts of North America. Qibla angles are given from true north, so an uncorrected compass reading will be off by the local declination.
Can I trust my phone's compass?
Usually yes, but with care. Phone magnetometers are disturbed by metal, magnets, speakers, car bodies and reinforced concrete. If the needle drifts or jumps, step away from metal objects and recalibrate by moving the phone in a figure-of-eight motion. Cross-checking with a second method the first time you pray in a new place is a good habit.
What is the qibla angle for Istanbul?
Approximately 152° clockwise from true north — that is, south-southeast. Ankara is about 160°, Izmir about 144°, and Erzurum about 184°. The angle grows as you move east across Türkiye: in the far east the direction turns almost due south and even slightly to the west of south.
How do I find the qibla without a compass?
Several methods work. During the day, the sun is due south at solar noon in the northern hemisphere, giving you a north-south line. At night, Polaris marks true north. Twice a year (around 27-28 May and 15-16 July) the sun stands directly above the Kaaba, and at that moment the shadow of any vertical object anywhere on the sunlit side of the Earth points away from the qibla. Finally, a nearby mosque's mihrab is a reliable reference.
Is my prayer valid if the direction is slightly off?
Yes. The majority of scholars hold that for anyone outside Mecca, facing the general direction of the Kaaba (jihat al-qibla) is sufficient; exact precision is not required. If you make a reasonable effort (ijtihad) and later discover you were off, the prayer already performed remains valid and does not need to be repeated.
What if I cannot determine the direction at all?
If no method is available — heavy overcast, unfamiliar surroundings, no phone — you make your best judgement and pray in the direction you believe to be correct. Prayer is not delayed until the direction becomes certain. Scholars are unanimous that a prayer performed after a sincere effort is valid even if the direction later turns out to have been wrong.
How do I find the qibla on a plane, train or bus?
In a moving vehicle, facing the qibla for the entire prayer is usually impossible, and the requirement is relaxed accordingly. Face the qibla at the start if you can, then continue as the vehicle moves. On aircraft, the in-flight map's heading combined with a qibla app in flight mode (GPS often still works by a window) gives a good approximation. For obligatory prayers, many travellers pray after landing when circumstances allow.
When and why was the qibla changed?
For roughly sixteen to seventeen months after the migration to Medina, Muslims prayed toward Jerusalem (Bayt al-Maqdis). In the second year after the Hijra the direction was changed to the Kaaba, as recorded in Surah al-Baqarah 2:144. The mosque where the change occurred mid-prayer is known as Masjid al-Qiblatayn — the Mosque of the Two Qiblas.
Why does a qibla compass sometimes point the wrong way?
The usual causes are magnetic interference (metal furniture, phone cases with magnets, car interiors, steel-framed buildings), an uncalibrated magnetometer, or a location fix that has not updated after travel. Turn off any magnetic accessory, recalibrate, confirm that the app has your current GPS position, and compare with a known reference such as a mosque before relying on the reading.
Does magnetic declination change over time?
Yes. The Earth's magnetic field drifts continuously, so declination values shift by a fraction of a degree per year and reference models are revised roughly every five years. For qibla purposes the change is too small to matter within a lifetime, but it is one more reason to prefer an app that computes the bearing from your coordinates rather than a fixed compass marking.
How does the qibla compass in Hatırla İslam work?
The app reads your position via GPS, solves the great-circle bearing to the Kaaba's coordinates, and corrects the device magnetometer reading for local magnetic declination — so the arrow points to true qibla, not magnetic qibla. It also warns you when it detects magnetic interference and asks you to recalibrate, and it works offline once your location is known.
