I say, and with God's success: Regarding the blood of istihada (irregular bleeding): 1) What the young girl sees, who has not yet reached nine years of age. 2) What the woman who has ceased menstruating sees, other than black and red. 3) What the pregnant woman sees without giving birth. 4) What exceeds the duration of the usual menstruation and postpartum bleeding to the second menstruation. 5) What is less than three days during the menstruation period. 6) What is outside the usual period to another menstruation, provided it exceeds ten days and the threshold is met. 7) What exceeds the usual duration, provided it exceeds ten days and the threshold is not met, refer to: Dhakhr Al-Mutahilin, pp. 102-104, and others, and God knows best.
