Is it permissible to perform supererogatory prayers and recite the Qur'an in a garment that became impure and was then moistened with a small amount of water?

If a ritually impure garment is purified in a legally prescribed manner, such as by washing it with water until the water separating from the washed area is not altered by the impurity, then it is considered pure and prayer in it is valid. However, if it is not purified in a recognized manner, it remains impure and prayer in it is invalid, whether it be a Fard (obligatory) or a Nafilah (supererogatory) prayer. The impurity of a garment does not prevent the recitation of the Quran; rather, purity is merely recommended for its recitation.
