Does a woman experiencing Istihada (abnormal, non-menstrual bleeding) prevent her from observing I'tikaf?

Primary text

Istihada does not prevent I'tikaf because it does not prevent prayer or circumambulation (Tawaf). Aisha reported that a wife of the Prophet (PBUH) experiencing Istihada would sometimes place a basin beneath her while praying during I'tikaf. She must take precautions, such as binding herself (tataḥaffaz) and using coverings, so as not to soil the mosque.
