Purification is divided into two categories: 1. Major purification: which is bathing from sexual impurity, menses, and post-partum bleeding; or its substitute, "tayammum" (dry ablution) from sexual impurity (major ritual impurity). 2. Minor purification: which is making ablution after urinating, defecating, or the like; or its substitute,"tayammum" from minor ritual impurity.
"Tat'heer": cleansing, purification from impurity. It is also used to mean exaltation and exoneration.
Removing the state of ceremonial impurity [i.e. janābah], or any impurity such as urine, to be able to pray.
