Purity: Prohibition of Touching Quranic Writing Without Wudu
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 316:
Touching the writing of the Qur’an – i.e. making a part of the body come into contact with the writing of the Qur’an – for someone who does not have wuḍūʾ is unlawful. However, if the Qur’an is translated into another language, then touching the translation is not a problem.
