Hadith and duas

The 99 Names of Allah

The list follows the narration in Jami' at-Tirmidhi 3507, without the name "Allah", and adds Al-Ahad from Sunan Ibn Majah 3861. The hadith that Allah has ninety-nine names is in Sahih al-Bukhari 2736 and Sahih Muslim 2677. Verses quoted with each name use the Quran sources above.

Prayer times

Times are calculated with Adhan, an open source library that implements the standard astronomical formulas. Each city uses its coordinates and time zone, including daylight saving changes, and the method most widely followed in that country. You can switch method and Asr convention on every page.

Hijri dates

Qibla direction

The Qibla is the great circle bearing (the shortest route over the Earth's surface) from your location to the Kaaba, taken as21.4225° N, 39.8262° E, measured clockwise from true north. A phone compass shows magnetic north, which can differ by several degrees, and the Qibla finder explains how to allow for that.

Zakat

The calculator uses the nisab of 85 grams of gold or 595 grams of silver and the rate of 2.5% on zakatable wealth held for a lunar year. You enter the current gold or silver price yourself, because prices change daily and differ between countries. Rulings on particular assets vary between scholars; ask a qualified scholar about your own situation.
