What is the ruling on purification (tahara) and prayer (salat) for a bedridden patient who has medical devices attached and a urine bag?

Prayer is obligatory for a Muslim in any condition as long as their intellect remains. They should pray standing; if unable, then sitting; if unable, then on their side; if unable, then reclining. If they are able toاء with water, they should perform it; otherwise, they should perform tayammum.

A sick person with a urinary catheter prays according to their condition, similar to someone with urinary incontinence or irregular bleeding (istiḥāḍa). They should perform tayammum if they cannot use water; otherwise, they should perform wuḍūʾ with it. Any discharge after wuḍūʾ does not invalidate it. However, one should not perform wuḍūʾ until after the prayer time has begun, and they should pray even if discharge occurs as long as the time remains. They should perform wuḍūʾ for the time of each prayer.
