Is the urine of a four-month-old infant girl impure, and what should the mother do when the infant urinates on her during prayer?

The urine of a female infant is impure (najis), and if it touches the body or clothes, the prayer is not valid until what has been defiled is purified. According to the Malikis, a nursing mother is excused for the urine and faeces of an infant (whether male or female) if she has striven to ward off the impurity but was unable to do so, and it is recommended for her to dedicate a garment for prayer. Prayer is the pillar of religion, and it must be performed on time and continuously; it is not permissible to be negligent in it. Whoever has missed prayers after puberty must make them up, and if the number is unknown, they should make up what they predominantly believe to be the case.
