Is the prayer of one who urinates in his bed without feeling it permissible?

Prayer is never waived for a mature Muslim. Whoever urinates in their sleep without awareness must purify their body and clothes from the urine before prayer. Prayer with impurities is not permissible. It is advised to use special bedding and clothes for sleeping, to wash the body upon waking, and to wear pure clothes for prayer. One should be careful not to pray on bedding contaminated with urine, even if it has dried, or to touch it with a wet body or clothes.
