Cleanliness has four stages:

1.Purifying the outward body from dirt and filth (like performing ablution and having a bath) 2.Purifying the limbs from breaking Allah Almighty’slaws & committing sins (like looking at haram, eating haram, lying and backbiting, tailbearing) 3.Purifying the heart from ill habits and blameworthy traits (like hatred, animosity, showing off etc) 4.Purifying the innerself (batin) from everything besides Allah Almighty (this is when every act is offered conciously for Allah Almighty and His pleasure) - Imam Ghazzali’s Iyha Ulum al-Din -
