❖ Question:
After becoming pure from menstruation, is a woman required to change her clothing, even if no blood or impurity has come into contact with it?
❖ Answer:
No, it is not obligatory for her to change her clothes after becoming pure from menstruation—as long as her garments are free from blood or impurity.
✔ Reason: Menstruation does not render the body itself impure,
✔ And the menstrual blood only renders impure that which it directly contacts.
Evidence from Sunnah:
The Prophet ﷺ instructed women that:
If menstrual blood gets on their clothes, they should wash it off,
Then they may perform prayer in the same clothing.
(Fatwa by: Shaykh Muḥammad ibn Ṣāliḥ al-‘Uthaymīn رحمه الله)❖ Summary:
✔ It is permissible to perform Ṣalāh in the same clothes worn during menstruation if there are no traces of impurity.
✔ Changing garments is not a requirement for prayer after purification from menstruation.
