What epochs in the history of Western Europe resemble the Muslim invasions of India? What are the similarities here?

The first Muslim invasion of India (the campaigns of Mahmud Ghaznewi at the beginning of the 11th century) resembles the first invasion of Western Europe by Muslims (at the beginning of the 8th century). The conquest of India by the Afghan Muslims in the 12th century is similar to the invasion of the Ottoman Turks into southern Europe in the 14th-16th centuries.
