Islamic art and architecture play a significant role in expressing religious beliefs by focusing on beauty, unity, and the divine. Through intricate geometric patterns, calligraphy, and arabesque designs, Islamic art reflects the infinite nature of God and avoids idolatry by refraining from depicting human figures. Mosques and other architectural structures are designed to create spaces of tranquility and reflection, helping worshippers feel closer to Allah and fostering a sense of communal devotion.
