Does the ruling on a woman interrupting the prayer include the mother and sister, for example, since the operative cause here is absent, which is fitnah (trial, discord or temptation)?

The questioner : As for the woman, it appears that the ruling includes the mother, the sister, and others.

The Shaykh : Yes.

The questioner : ...

The Shaykh : Yes, but the operative cause derived by scholars is not necessarily applicable in all cases. This is a rule you should keep in mind: the derived operative cause is not necessarily applicable in all cases, whereas the cause stated by the Shari'ah is necessarily applicable in all cases.
