Touching or scratching the genitals

Q: Does touching or scratching the genitals nullify a person’s Wudu’ (ablution) even if from above the clothes and this does not stir sexual desire?

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions. Touching the private parts (frontal or anal) while uncovered, nullifies Wudu’ even if this does not stir sexual desire. (Part No. 5; Page No. 266) But if the touch is from behind a barrier, Wudu’ is not nullified.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
