Map - Dhaid (Adh Dhayd)

Dhaid, or Al Dhaid (ٱلذَّيْد), is the capital of the Central Region of the Emirate of Sharjah in the United Arab Emirates. An oasis town, it has extensive irrigated date palm plantations with water channelled from the nearby Hajar mountains, at least in part through ancient tunnels dug for that purpose, known as aflāj in Arabic (falaj in the singular).

Dhaid has long occupied a strategic location in the mouth of the important Wadi Siji.

An archaeological site discovered here in 2015 shows evidence of habitation by humans going back hundreds of thousands of years to the Stone Age. In particular, awls for piercing holes in the leather of animal hides, scrapers for cleaning leather, and stone axes were found here.

At the turn of the 20th century, Dhaid consisted of some 140 houses, owned by sections of the Tanaij, Bani Qitab and Khawatir tribes, including larger houses with mud brick towers. It also had a four-towered Al-Qasimi fort, featuring two round and two square towers, Dhaid Fort.

The town was maintained for the Ruler of Sharjah by a walī (وَلِي), who would collect tithes in the form of dates, as well as water rates (paying 228 Maria Theresa thalers in 1906). These revenues became core to a dispute of Al-Qasimi family over Dhaid in the 1920s. Dhaid became the seat of the deposed Ruler of Sharjah, Sheikh Khalid bin Ahmad Al Qasimi when, in June 1927, an agreement was reached between Sultan bin Saqr Al Qasimi and Khalid bin Ahmad to provide for the upkeep of the deposed ruler's family. This ceded the fort at Dhaid and the revenues of the inland oasis town to Khalid bin Ahmad. Dhaid, in 1906, generated some 228 Marie Theresa Dollars annually in water rates, as well as revenue from the sale of dates. Although he had Sultan bin Saqr's agreement, Khalid remained in Umm Al-Qaiwain, and sent some of his men to Dhaid to occupy his newly acquired property, as the Bedouin who had manned the fort for Sultan were still active in the area. With the support of the Sheikhs of the Bedouin tribes of Bani Ka'ab and Na'im, who favoured any scheme which would weaken Sharjah, it was agreed that the ruler of Ras Al Khaimah, Sultan bin Salim Al Qasimi, would possess Dhaid 'on behalf of Khaled bin Ahmad'. This arrangement was not fully supported by Sultan bin Salim himself, who feared antagonising Saq bin Khalid, and also believed Khalid bin Ahmad would represent an ongoing financial burden with little hope of any return other than conflict. Khalid bin Ahmad finally took full possession of Dhaid in his own right in July 1928.
