The World Federation One Stop Fiqh

Ruling 466

It is recommended that at the time of prayers, a ḥāʾiḍ should clean herself of the blood, change the piece of cotton and the sanitary pad [or other absorbent item that a woman would normally use to absorb the discharge of blood], and perform wuḍūʾ; and if she cannot perform wuḍūʾ, she should perform tayammum. It is also recommended for her to sit in the place of prayers facing qibla and to engage in remembering Allah (dhikr), reciting duʿāʾ, and invoking blessings upon Prophet Muḥammad (Ṣ) and his progeny (ṣalawāt).
