Are Blister Fluids from Arba’een Pilgrims ‘Impure’? The Short, Surprising Answer

Tuesday, August 26, 2025

Clear, non-bloody blister fluid from long pilgrimages is usually not classed as impure — but once blood or infection appears, the ruling changes and you should cover up and check with a doctor and your marja‘.

Are Blister Fluids from Arba’een Pilgrims ‘Impure’? The Short, Surprising Answer

While walking the Arba’een pilgrimage, people’s feet may develop chickenpox or blisters. If these blisters open, is their discharge impure — and can a pilgrim enter a mosque or shrine while in that condition?

Your question is highly relevant to the special conditions of Arba’een pilgrims. Answering it requires examining several points:

Type of blister or vesicle

Type / Condition

Ruling

Blisters caused by varicella (chickenpox) or cowpox, without blood contamination

The discharge is considered pure.

Blisters caused by burns, friction (rubbing), or infected blisters that are contaminated with blood

The discharge is considered impure.

General rule

If the blister is purulent (contains pus) or bloody, it is impure; if the fluid is clear and odorless, it is pure.

Cause of the lesion

Cause

Ruling

Infectious or blood-borne disease

The discharge is impure.

Physical causes (excessive walking, rubbing) and not contaminated with blood

The discharge is pure.

In short: blister fluid that is pus-like or bloody is impure, while clear, odorless discharge is considered pure.

Recommendations

  • See a doctor: For an accurate diagnosis of the type and cause of the blister or vesicle, consult a physician.

  • Ask your marja‘ (religious authority): After medical diagnosis, consult your marja‘ to get a definitive religious ruling on the discharge.
