Assalaamu aleykum.

I read on this Fatwa that a small amount of impurity is overlookable, according to Abu Hanifah, and that was the view favored by ibn Taymiyyah, and according to the same Fatwa that view is correct.

But later on in the fatwa it confuses when it states:

"Among the small amounts of impurity that may be overlooked because it is too difficult to guard against it is a small amount of urine in the case of one who suffers from incontinence but tries to guard against it as much as he can."

Does that meean that there has to be similar conditions for the small amount of impurity to be overlookable (such as incontinence) or can the small amount of impurity be overlooked at any time with any person (wether sound or not)?

I could mention I asked the IslamToday Fatwa service this question too, but got no response. So please answer this question if you know. Jazakum Allaah khayr.
