Turbah is a special type of small, flat clay or soil tablet used by some Muslim people during prayer. It's usually no bigger than a coin or a small stone. The word "turbah" actually means "soil" in Arabic.
When Muslims pray, they usually do it on a special mat or rug, called a prayer mat or a prayer carpet. But before they start praying, some Muslims like to use a turbah. They put it on the ground or on their prayer mat, and then they put their forehead on it while they pray.
Why do some Muslims like to use a turbah? Well, it's because they believe that it's important to show humility and connection to the Earth while praying. They think that putting their forehead on a piece of soil or clay helps them stay focused during prayer and feel more connected to God and the world around them.
Some Muslims choose to use a turbah made from the soil of a holy place, like the city of Karbala in Iraq where the Prophet's grandson, Imam Hussain, was martyred. They believe that using a turbah from a holy site brings them even closer to God during prayer.
So overall, turbah is just a small piece of clay or soil that some Muslims like to put on the ground during prayer to help them feel more focused and connected to God.
