What is the ruling on fasting, prayer, and touching the Qur’an on the day one bathes after the cessation of menstrual bleeding, given that the blood later returns in the form of light brown streaks, and how should a woman act in this situation?

The blood a woman sees in the first few days is considered menstruation. If she then sees purity, she must perform ghusl (ritual bath) and pray. If she sees a yellowish or brownish discharge after performing ghusl, it is not considered anything (i.e., not menstruation), and she remains pure, performing istinja (cleansing) and wudu (ablution) for prayer. However, if the blood returns, she is considered menstruating again. Her previous state of purity before the return of menstruation is valid; thus, there is no sin upon her for touching the Mushaf (Qur'an), praying, or fasting during that period of purity.
