Is it permissible for a bedridden person who cannot control their urine and whose urine flow is continuous to perform wudu for more than one prayer?

The prayer of one who carries impurity in a bottle or the like is not valid under normal circumstances. However, if it is difficult for the questioner to remove and replace the bag for every prayer because the urine does not stop, then he is excused in this case. If urine exits continuously, then ablution is required for every prayer. And if performing ablution for every prayer is extremely difficult for you, there is no blame upon you for combining two prayers with one ablution, following the Maliki school of thought.
