Classical Age of the Ottoman Empire
Expansion continued during the first half of the reign of Suleiman I (r. 1520-1566), who conquered first Belgrade (1521) and Rhodes, before invading Hungary in 1526, defeating and killing King Louis II in the Battle of Mohács and briefly occupying Buda. Lacking a king, Hungary descended into civil war over the succession, and the Ottomans gave support to John Zápolya as a vassal prince. When their rivals the Habsburgs began to achieve the upper hand, Suleiman directly intervened by again conquering Buda and annexing it to the empire in 1541. Elsewhere, Suleiman led major campaigns against Safavid Iran, conquering Baghdad in 1534 and annexing Iraq. Ottoman rule was further extended with the incorporation of much of North Africa, the conquest of coastal Yemen in 1538, and the subsequent annexation of the interior.
Sabaeans
The Sabaeans are mentioned in the Qur'an twice as "Qawm Saba’" (, people of Saba). The Qur'an mentions the kingdom of the Saba in the 34th Chapter. The Qur'anic narrative, from sura 27 (An-Naml),[5] has Suleiman (Solomon) getting reports from the Hoopoe bird about the kingdom of Saba, ruled by a queen whose people worship the sun instead of God. Suleiman (Solomon) sends a letter inviting her to submit fully to the One God, Allah, Lord of the Worlds, according to the Islamic text. The Queen of Saba is unsure how to respond and asks her advisors for counsel. They reply by reminding her that they are "of great toughness" in a reference to their willingness to go to war should she choose to. She replies that she fears if they were to lose, Suleiman may behave as any other king would: 'entering a country, despoiling it and making the most honorable of its people its lowest'. She decides to meet with Suleiman in order to find out more. Suleiman receives her response to meet him and asks if anyone can bring him her throne before she arrives. A jinn under the control of Suleiman proposed that he will bring it before Suleiman rises from his seat. One who had knowledge of the "Book" proposed to bring him the throne of Bilqis 'in the twinkling of an eye' and accomplished that immediately.[6] The queen arrives at his court, is shown her throne and asked: does your throne look like this? She replied: (It is) as though it were it. When she enters his crystal palace she accepts Abrahamic monotheism and the worship of one God alone, Allah.
