Perform ritual washing regularly according to Islamic teachings .

This hadith is about the importance of performing ghusl, or ritual washing, in Islam. It was narrated by Musa Al Juhani that Mujahid was given a vessel which he estimated to be eight ratls. Aishah then told him that the Prophet Muhammad used to perform ghusl using such a vessel. This hadith shows us how important it is for Muslims to perform ghusl regularly as part of their religious practice and how even something as small as an amount of water can be enough for this purpose. It also teaches us about the importance of following the example set by Prophet Muhammad in our daily lives and striving to emulate his actions in all aspects of life.
