Purity: Definition of Nifas

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 497:

From the time the first part of a baby’s body comes out of its mother’s womb, the bleeding that a woman experiences for ten days is the bleeding of nifās, on condition that it can be called ‘the bleeding of childbirth’. A woman in the state of nifās is called a ‘nufasāʾ’.
