How does one perform ablution (wudu') for Friday Prayer and the rituals of Umrah if they suffer from continuous dripping of urine after urination?

A person is considered to have incontinence if urine continues to flow throughout the prayer time, such that they do not find a period when the urine stops to perform prayer with valid purification. However, if they do find sufficient time to perform prayer with valid purification, they must wait and pray during that time. What a person with incontinence should do for Friday prayer and how to perform 'Umrah has been previously explained.
