Is a person excused if they miss congregational prayers and Friday prayer due to side effects from surgery, such as frequent urination and severe pain, in addition to suffering from an overactive bladder?

The sick person who is unable to attend congregational prayers (jama'ah) and Friday prayers (Jumu'ah) is excused. The warning mentioned for those who abandon three Friday prayers out of negligence does not apply to him, because this warning is specific to the negligent, and the sick person abandons them due to his inability. One should not pay attention to the whispers of Satan that suggest hypocrisy or God's lack of love for the sick person.
