Are the drops of urine that descend after urination, whether they get on clothing or not, excusable, and is the prayer considered valid in this case?

The ruling was based on the premise that the questioner suffers from urinary incontinence ( سلس البول), but it did not specify the extent to which the impurity (حدث) becomes incontinence. It also did not differentiate between a person with incontinence and others. Then, it considered the person to be excessively scrupulous (موسوس) and advised them not to pay attention to those drops, nor to be required to change their clothes, nor for their ablution to be invalidated.

This answer can be considered valid within the Maliki school of thought if the conditions for considering something incontinence and the difficulty of avoiding impurity are met. The criterion for this in their view is that incontinence does not invalidate ablution if it persists for half or more of the time of the prayer periods. Impurity is excused unless the impurity becomes deeply rooted (يستنحكه الحدث). However, if it does not reach the level of incontinence, then ablution is invalidated by the discharge, and one is required to purify or change their clothes.
