Jabal Dakkā (Arabic: جَبَل دَكَّا) or "Mount Daka", is the highest mountain in the area of the town of Ash-Shafā,[1] about 20 km (12 miles) from the city of Taif, located in the western region of Saudi Arabia.

[2] The height of the top of the mountain is between 2,500 and 2,900 metres (8,200 and 9,500 feet) above sea level, this has caused a controversy with the timing of the sunset for Ramadan, as the sun stays on the peak two minutes longer than the surrounding area.

To resolve the controversy a panel of religious scholars visited the mountain to observe sunset.

[3] The committee of legitimacy, including a member of the Supreme Council of Saudi Scholars Abdullah al-Mutlaq determined that the peak need not adhere to calendar.

The mountain is used to know the dates of prayer, fasting and breakfast in the month of Ramadan.
