Answer:
Prophet muhammad (صلاله عليه وسلام) had a vision of the ottoman empire being conquered by the muslims .There is even a Hadith in which the Prophet (PBUH) prophesied the Atraq, who in Arabic; were the Turks. And at first, when the Mongols had come to power, some scholars of Islam thought that they were the ones who were prophesied. However, the proofs did not add up at all. Then, when the Ottoman Turks came to rule the power, the whole of the Islamic scholars came to the conclusion that they were the ones mentioned in the Hadiths: “The Turks will ride to the inner side of the Arabian Peninsula” and he also said that; “The Turks will be the first nation whom will take the Caliphate from the hands of his Ummah.” This means that, they were nominated a solid candidate among the Muslim peoples for the Muslim Caliphate by the Holy prophet. Also, the Prophet too mentioned once; “Do not fight the Turks, for whoever fights the Turks will lose”.
And of course there is also the famous Hadith: "Verily you shall conquer Constantinople. What a wonderful leader will he be, and what a wonderful army will that army be!" and "The first army that goes on expedition to Constantinople will be forgiven." And so the Prophet Muhammed (PBUH) himself had praised the Turks, and on many occasions, had prophesied their great empires that were to come.
