All perfect praise be to Allah, the Lord of the worlds. I testify that none is worthy of worship except Allah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.
We praise Allah Almighty for guiding our questioning sister to the truth and to asking about the rulings of her religion. Moreover, we ask Him to keep her steadfast on guidance. Concerning her question about doing matters that arouse her sexual desire during fasting while ignoring whether she discharged something or not, this does not invalidate fasting. She is not required to make up fasts or offer an expiation. She should repent to Allah Almighty from deliberately doing matters that arouse one’s sexual desire while fasting.
Allah knows best.
