Ruling 429

Whenever ṣalāt al‐āyāt becomes obligatory on a mustaḥāḍah during the time of the daily prayers and she wants to perform both of them one after the other, then based on obligatory precaution she cannot perform both of them with one ghusl and wuḍūʾ [and she would need to perform an additional ghusl or wuḍūʾ].
