How to Manage Ongoing Ritual Impurity

Q: How do I properly manage purification if I experience an ongoing state of ritual impurity such as incontinence?

A: It is obligatory upon anyone whose state of ritual impurity (hadath) is ongoing—such as a mustaḥāḍah (a woman with non-menstrual vaginal bleeding), or someone suffering from urinary incontinence, continuous madhī (pre-orgasmic fluid), gas, a wound that does not stop bleeding, or persistent nosebleed—to:

1. Wash the area soiled by the impurity, in order to remove the impurity;

2. And to cover or bind it, meaning: take all reasonable steps to prevent the impurity from exiting—such as stuffing the area with cotton and wrapping it with a pure cloth.

If binding is not possible they pray according to their condition.

It is not obligatory to repeat washing and binding for each prayer so long as one has not been negligent in that regard, because the impurity is overwhelming and cannot reasonably be prevented.

One who suffers from ongoing  hadath (state of impurity) must perform wudu’ at the time of each prayer if anything exits. This is because this is a case of ritual purification for an excuse, which is therefore tied to the time of prayer, similar to tayammum.

If nothing exits, the wudu’ is not invalidated.

It is recommended (mandūb) for someone with ongoing impurity to pray immediately after purification.

If the person with continuous impurity habitually experiences a pause that lasts long enough for both purification and prayer, then the obligation is to perform the obligatory prayer within that period—because it becomes possible to perform the prayer without excuse, and thus it is treated like one without an excuse.

If the pause unexpectedly occurs for someone whose normal state is continuity, and it lasts long enough to purify and pray, then his/her wudu’ is invalidated—because he/she is now in the ruling of one whose impurity is not continuous.
