The Ottomans added many lands to Dar Al-Islam, including Constantinople. They struck fear into the hearts of kuffar from Lisbon to Moscow. They helped defend many Muslim lands from kuffar colonisation, such as Ajuuraan, Adal, Aceh, Algeria, Libya, and the Dervish State. They defended Sunnis in Iraq from the Safawi menace. When they were in power, the Ummah was respected and feared across the globe.
How much lands have the Saudis and Wahhabists added to Dar Al-Islam? How many Muslim lands have they defended? How much respect and prestige have they brought to the Ummah's name?
