Is it sufficient to sprinkle water on the area of the blood to perform prayer when trousers are contaminated with wound blood?

Washing blood is required to purify a garment, and sprinkling is not sufficient. A small amount of blood is overlooked according to the majority of scholars, though they differ on what constitutes a small amount. Some have defined it as the size of a Baghdadi dirham, while others have defined it by custom, as that which the heart does not consider to be excessive.
