Purity: Acts Conditional on Wuḍūʾ (Non-Prayer)
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 425:
If a woman with slight or medium istiḥāḍah wants to perform an act – other than prayers – that is conditional on having wuḍūʾ – for example, she wants to touch the writing of the Qur’an with a part of her body – then, in the event that this is after finishing prayers, she must, based on obligatory precaution, perform wuḍūʾ, and the wuḍūʾ that she had performed for prayers will not suffice.
