Is the hair that necessitates blood (ritual expiation) upon its falling only from the head and beard, or does it include all body hair? And is blood due for every hair that falls when running fingers through the hair to let water reach the scalp, or during ritual cleansing (istinja'), and how can one know the number of fallen hairs and whether they are alive or not?

A pilgrim in a state of ihram (definition) is prohibited from removing hair from any part of their body, based on the Almighty's saying: "And do not shave your heads until the sacrificial animal reaches its place of slaughter." The expiation (fidyah (definition)) required for removing hair is optional: fasting for three days, or feeding six poor persons, or sacrificing a sheep. There is no difference between one who does this intentionally or out of necessity. This expiation becomes obligatory for shaving more than two hairs. For less than that, such as a single hair, the expiation is feeding one poor person, and for two hairs, it is feeding two poor persons. It is permissible for a pilgrim in ihram to run their fingers through their head and the rest of their hair if they are certain that no hair will fall out. If three or more living hairs fall out, expiation is required; if the hair is dead, no expiation is required.
