The Quba Mosque (Quba' Masjid or Masjid al-Quba, Arabic: مسجد قباء), in the outlying environs of Medina in Saudi Arabia, is the oldest mosque in the world.

See photo: "In this photo you can see the (Bedu) traditional black tent, but the round tent in the foreground is a "Saudi" tent, which is used in Wadi Rum much more than usual in Jordan."

Bedu/Beduin use woven goat/sheep hair rectangular black tents (beit/bet). Arabs traditionally used round leather skin white tents (quba/qubba) which appear evolutionarily in between the Lapp/Sami conical reindeer skin tent (cote/goati/kota), the Dakota tipi (dwelling of bison skins), the Turkish ui (yurt) of sheep felt, and the Mongol ger (yurt) of sheep felt.

A qubba (also written koubba etc.) is an Arabic word for tomb, especially Muslim domed mausoleums or just the dome of a tomb, or any type of building with a dome, such as the Dome of the Rock (Qubbat al-Sachra). Originally it meant a tent of hides.^[
 
"In Islam, the term qubba is generally attributed to a religious funerary monument (tomb) whose plan is centred under a cupola (cup-bola dome). It is, however used to describe a monument with a similar layout but different functions, like a kiosk in a garden or a mosque".
 
"The Qubba’s interior is crowned with a ribbed dome, whose stucco decorations are reminiscent of caliphal Andalusian art. Large, poly-lobed horseshoe arches sit directly on the square-based cornice that constitutes the dome’s skeleton. They cross with one another, transmitting the square plan into an octagonal one whose pendentives are richly decorated with floral patterns incised around a strongly projecting scallop. This motif was very common in classical Antiquity and echoes the rich classical influences of Tingitan Mauritania[4]. In the corners the empty spaces are covered with muqarnas arches. These decorative elements originated in Iran and were probably transmitted to Cairo in the Fātimid era, then to the Muslim West[5].

A drum serves as a transition between the large arches and the small terminal dome (in Andalusian tradition) that completes the ensemble. This octagonal level is made up of small recticurvilinear arches, which seem to have been an Egypt inspiration. They can also be seen in the Great Mosque at Tlemcen (end of the eleventh to the beginning of the twelfth century), in Cairo in the shrine of Sayyida ‘Ātika (1100–1120), and in Spain in the Aljaferia at Zaragoza (second half of the sixteenth century)." http://www.qantara-med.org/qantara4/public/show_document.php?do_id=781&lang=en
