What is the term for physical impurity, such as urine or blood, distinct from the ritual state of impurity requiring Wudu or Ghusl?

Explanation

– Najasah refers to physical impurity, such as urine, blood, or similar substances, which must be physically removed from the body, clothing, or prayer area, distinct from the ritual state of impurity addressed through Wudu or Ghusl.
– This concept requires the physical cleaning of the affected area or item, separate from and in addition to the ritual purification required before prayer.
– For exams, note that both physical cleanliness (removing Najasah) and ritual purity (addressing Hadath) are generally required together for the valid performance of Salah.
