Tayammum is a ritual purification method in Islam that is used when water is not available or when a person is unable to use water due to a valid reason, such as illness or unavailability of water. Here’s how to perform tayammum: Intention (Niyyah): Begin by making a sincere intention in your heart for tayammum. Your intention should be to perform tayammum as a substitute for wudu (ablution) or ghusl (ritual bathing) when necessary. Strike the Ground: Find a clean and dry surface, like sand, dust, or earth (free from impurities), and gently strike it with your hands. Wipe the Face: Using both hands, wipe your face once, starting from your forehead to your chin, making sure to cover the entire face. Wipe the Hands: Wipe your right hand with your left hand and your left hand with your right hand, ensuring that you wipe from your fingertips to your wrists. Intentional Stroke: These actions should be performed with intention, mindfulness, and respect.Prayer or Ghusl: You can now perform your prayer or any other religious activity that requires purification. Tayammum can also be used as a substitute for ghusl by repeating the above steps twice. It’s important to note that tayammum is a substitute for wudu or ghusl when water is not available or its use is not possible due to valid reasons. Once you have access to water, you should perform wudu or ghusl as appropriate and repeat any missed prayers or religious activities. Tayammum is a temporary solution and should be used when necessary, with the intention of fulfilling your religious duties in situations where water is unavailable or cannot be used.
