The Arabic word for purity and cleanliness is Taharah. Taharah is one of the most important duties for a Muslim.
Taharah means cleanliness of the :
1) mind and soul
2) body and clothes
3) home and surroundings
We keep our minds and souls clean by not having evil thoughts nor doing evil deeds. We keep our bodies and clothes clean by washing them regularly. We keep our homes and surroundings clean by being tidy and hygienic, and not littering or polluting. If a Muslim is not Tahir, pure and clean, then he cannot perform Salah or touch the Holy Qur’an. Therefore a Muslim always stays clean. The angels are pure and clean and remain close to those who are pure and clean. shaytan is impure and unclean and is always close to those who are impure and unclean. Allah only loves those who are pure and clean.
And they ask you about menstruation. Say, “It is harm, so keep away from wives during menstruation. And do not approach them until they are pure. And when they have purified themselves, then come to them from where Allah has ordained for you. Indeed, Allah loves those who are constantly repentant and loves those who purify themselves.” 2:222 Surat Al-Baqarah (The Cow) – سورة البقرة
Abu Malik at-Ash’ari reported:
The Messenger of Allah (ﷺ) said: Cleanliness is half of faith and al-Hamdu Liliah (Praise be to Allah) fills the scale, and Subhan Allah (Glory be to Allah) and al-Hamdu Liliah (Praise be to Allah) fill up what is between the heavens and the earth, and prayer is a light, and charity is proof (of one’s faith) and endurance is a brightness and the Holy Qur’an is a proof on your behalf or against you. All men go out early in the morning and sell themselves, thereby setting themselves free or destroying themselves.
