Q. What is the significance of muslim cap in Islam?

Answer

While it is not obligatory to cover one's head during salah, it is part of the Islamic etiquette to do so. If a Muslim prays without a head covering out of a desire for simplicity and modesty, his or her prayer is still accepted. Nonetheless, if a man does not cover his head for reasons of style or laziness, his prayer is invalidated. It's worth noting that people of various faiths, like Zoroastrians, Christians, and Jews, also often wear head coverings. However, the custom of wearing a head covering is more common among Muslims. Here are several reasons why Muslims may choose to cover their heads with a scarf or a hat.
