Najis

Najis is a word that means something is not clean in Islam. It is very important to keep things clean in Islam because they believe it makes Allah happy. When something is najis, it means that it is not allowed to be used for prayer or worship. This can include things like bodily fluids such as urine, feces, and blood. Animals that Muslims are not allowed to eat, such as pigs, are also considered najis.

To become clean again, Muslims have to perform a special cleaning ritual called "wudu" or "ablution" before prayer. This involves washing certain parts of their body with water and being careful not to touch anything that is considered najis. If they accidentally touch something najis, they have to clean themselves again to become clean for prayer.

In summary, najis means something is not clean in Islam and it's important to keep things clean for prayer and worship. Muslims perform a cleaning ritual called "wudu" before prayer.
