Step-by-step explanation:
Suleiman believed that his empire's mosques would be pleasing to Muhammad due to their architectural grandeur. The Ottoman sultans, including Suleiman, patronized the construction of mosques as an opportunity for self-promotion and to display their wealth and power. The mosques were often part of larger complexes known as kulliyes, which provided extensive social services such as soup kitchens, hospitals, schools, and public baths. Additionally, the decoration and artwork in these mosques, such as intricately-carved wooden minbars and handcrafted metal lamps, showcased the highest caliber of craftsmanship and attention to detail.
