Ahl al-bayt is an Arabic term that refers to the family of the Prophet Muhammad. It includes his wife, Fatima, his sons, Hasan and Husayn, and their descendants. Basically, it’s like saying the family of the Prophet Muhammad.
Just like how you have a family with your mom, dad, siblings, and grandparents, the Prophet Muhammad had a family too. In Islam, the family of the Prophet is very important, and they are respected and loved by Muslims all over the world.
The Prophet’s family taught people how to live good lives according to the teachings of Islam, and they are considered to be role models for Muslims. Muslims often listen to the stories and teachings of the Prophet’s family to learn more about Islam.
So, ahl al-bayt is just a special way of talking about the family of the Prophet Muhammad.
