Does the ablution of a person with سلس (urinary incontinence) – whose سلس (incontinence) only accompanies them during prayer – become invalidated upon the expiration of the time for the prescribed prayer for which they performed ablution, if they did not perform it?

One who constantly passes wind during prostration, and it does not stop for enough time to perform ablution and prayer, is considered to have incontinence (Saahib al-Sals). Scholars have differed regarding the nullification of the ablution of one with incontinence upon the expiry of the time for the obligatory prayer for which he performed ablution.
