Perform tayamumm when there's no access or availability of water

This hadith explains the importance of tayammum, which is a form of ritual purification in Islam. It is used as an alternative to wudu when water is not available. In this hadith, 'Ammar bin Yasir was on a camel and could not find any water, so he rolled in the dust like an animal. He then went to the Prophet Muhammad and told him about his situation, and the Prophet said that tayammum would have been sufficient for him instead of rolling in the dust. This teaches us that even if we are unable to perform wudu due to lack of access to water, we can still perform tayammum instead as it will be accepted by Allah SWT. We should also remember that cleanliness and purity are important values in Islam and should strive for them even if it means performing tayamumm instead of wudu due to lack of access or availability of water.
