Prioritizing the Custom or Distinction in the Case of a Woman with Irregular Non-Menstrual Bleeding

Question:
The Shaykh: If a woman with irregular non-menstrual bleeding has a customary pattern and a means of distinguishing her bleeding, which takes precedence?

Answer:
The customary pattern takes precedence, because the Messenger (peace and blessings be upon him) ordered that the customary pattern be given priority; it is the first thing, and the customary pattern is the clearest and most distinct thing? No.
