What is meant by "yellowish discharge" (ṣufrah) and "turbid discharge" (kudrah), and how is the timing of their connection or disconnection from menstruation determined? And are they considered part of menstruation if connected to it, as narrated by Aisha (may Allah be pleased with her): "We used to consider the yellowish and turbid discharge as part of menstruation if connected to it"?

Yellowish and brownish discharges are yellow or turbid blood. They are not pus, nor are they non-sanguineous as claimed. Their connection to menstruation is when a menstruating woman does not experience purity between the menstrual blood and these discharges. It is not correct to determine the separation between them by hours. What was narrated from 'A'ishah with the wording "We used to consider the yellowish and brownish discharges as menstruation" is weak, even if something close to its meaning was authentically reported from her.
