Is intercourse permissible during the five days preceding menstruation, knowing that a viscous fluid is discharged during this period?

What you see of discharge containing turbidity during your days of purity and before menstruation is not considered menses, according to the statement of Umm Atiyyah: "We did not consider turbidity and yellowness to be anything." During this period, you should pray and fast, and it is permissible for your husband to have intercourse with you, until you see menstrual blood.
