Is there any problem if the water used for ablution splashes onto clothes?

The water used in ablution and ghusl is called ‘mâ-i musta’mel’ (used water). Even though ‘used water’ loses its ability to remove ritual impurity (hades), it is not considered impure (najis). Therefore, such water does not make the place it touches dirty. (Mevsılî, el-İhtiyâr, 1/16)
