Is there some darkness and yellowing after the blood stops, meaning it continues for a period in the woman, so is it permissible for her husband to have intercourse with her?

The questioner : O our Shaykh, when the blood stops in a woman, without it stopping completely, does her husband have intercourse with her?

The Shaykh : How can the blood stop without it stopping? This is a statement that contradicts its beginning with its end, and its end with its beginning!

The questioner : There is some darkness and yellowing after the blood stops, meaning it continues for a period in the woman, so does her husband have intercourse with her, meaning sexual intercourse?

The Shaykh : O my brother, is it her custom or is it not her custom?

The questioner : The matter is customary for her, meaning these other colors continue with her for a period.

The Shaykh : Are these colors the completion of the blood, the black blood of menstruation, or is this in a state other than the custom?

The questioner : The completion of the blood.

The Shaykh : Then she is menstruating.

The questioner : She is menstruating.

The Shaykh: Yes.
