Purity is the Essence of islam
Purity (Tahârah) is a beautiful word that is pleasing to the eye, and a quality which everyone wishes to maintain.
Observing cleanliness of the soul, the clothes, and the surroundings is obligatory upon every Muslim, and this is considered as one of the Major quality in Islam. From an Islamic perspective, purity has a general meaning. Thus it may mean, on one hand, physical cleanliness which is the purity (of the body) from perceptible filth or ritual purification. On the other hand, it may mean spiritual purity which is the purity of the self from vices, sins and abandoning disobedience, and getting used to good deeds and words.” As we want to be clean from outside, we should also take serious action to clean ourselves from inside.
Before offering prayers, it is necessary to perform wudu, and in certain cases, both wudu and ghusl. The purifying agent is always pure water. However, during times when water is not available or is scarce, symbolic wudu and ghusl can be performed with clean dry earth which is known as Tayammum.
A person must not touch the Quran if the person is not in the state of Tahara. The Quran says: None shall touch it but those who are clean.
Purity (Arabic: طهارة, Tahara(h)) is an essential aspect of Islam. so we should maintain it.
