Is ghusl obligatory for a woman if she wakes up from sleep and finds no trace [of wet dreams], then some discharge comes out after urinating, knowing that she does not recall an احتلام (wet dream), and that this discharge differs from the description of maniy (spermatic fluid) that she knows after fulfilling desire?

If a woman does not recall having a wet dream and finds no wetness upon waking, and the fluid discharged after urination does not have the characteristics of manī (sperm/seminal fluid), then ghusl (ritual bath) is not obligatory for her, as it is not manī. Even if it were manī, ghusl would not be obligatory from it if it was not discharged with pleasure and gushing, according to the majority of scholars. We advise against succumbing to these obsessive thoughts.
