Is it permissible to pray with the ablution one performed at home, knowing that ablution is obligatory for every prayer due to discharge, and it is difficult to go out to perform ablution again before the prayer?

The jurists differed regarding the purity of vaginal discharge. The Hanafis and Hanbalis held that it is pure, while the Malikis and some Hanafis considered it impure. The Shafi'is divided it into three categories: definitively pure, which is the external discharge; definitively impure, which comes from the inner part of the vagina; and pure according to the more sound opinion, which is what the penis of the cohabiting partner reaches.

Some scholars, such as Sheikh Ibn Uthaymin, differentiated between discharge exiting from the birth canal and that exiting from the urinary opening, considering the former pure and the latter impure.

Both types invalidate ablution. Whoever experiences an impure discharge must wash whatever it touches of her clothes or body. For a pure discharge, it is recommended for her to do so. In both cases, she must perform ablution.

If the discharge is continuous, the woman must perform ablution for each prayer after its time has entered, and she should pray, and whatever comes out does not harm her. If it is intermittent, she should delay the prayer until the discharge stops, unless she fears the time will expire, in which case she prays, and whatever comes out does not harm her.
