Is it necessary to make ghusl after swimming in a pool?

Answer

Your question is ambiguous. If by pool you mean a public pool where all and sundry swim, then firstly it is not permissible to swim in such a filthy najaasat-filled pool. Such a diseased pool is polluted with both physical and spiritual najaasat. In addition to it being forbidden to swim in filth, ghusl is necessary. If by pool you mean your house swimming pool, then there are different cases.

* If the pool is small, i.e. it is less than the Dahdardah size (10 x 10 cubits), and you are in the state of janaabat, the water is rendered impure with your first plunge. Ghusl is Waajib and all the water has to be drained.

* If the pool is Dahdardah size and you are not in the state of janaabat, there is no need for ghusl afterwards. * If the pool is a large one, i.e. Dahdardah or more, and you are in the state of janaabat, the swim will substitute for the ghusl. Water has to be applied into the nose, and the mouth must be rinsed since this too is Fardh. Dahdardah is approximately 25 square metres.
