Does prayer become invalidated if one smells the odor of urine and there are yellow stains when changing clothes?

The ruling on one who prays with impurity on their body, clothes, or place, and only discovers it after completing the prayer, has been detailed in Fatwa No. 32789. If the emission of urine is due to سلس (incontinence), then there is no issue, but a garment for prayer should be acquired. Please refer to Fatwa Nos. 31631 and 35854.
