Is it permissible for a patient suffering from schizophrenia and megalomania, who takes medication that causes frequent urination and flatulence, to combine prayers, given that performing ablution for each prayer is a hardship and negatively affects his psychological well-being?

If the urine stops for a period sufficient for ablution and prayer, then the questioner is not considered to have incontinence. Similarly, frequent passing of wind does not signify incontinence unless it is continuous and involuntary.

It is not permissible to combine prayers if there is no difficulty in performing ablution and standing for prayer. Combining prayers without a legitimate excuse is considered a major sin. It is permissible to combine prayers if performing ablution or standing for it causes difficulty and weakness.

One of the best solutions is to pray the first prayer at the end of its time, then pray the second prayer at the beginning of its time.
