Is it permissible to read the Qur`an without making wudu` [ablution]?

It is obligatory upon whoever wants to read from the Qur`an to purify himself from both minor and major ritual impurity because of the hadith narrated by Ali [may Allah be pleased with him] who said: “I saw the Prophet ,upon him blessings and peace, perform wudu`, recite some verses of the Qur`an and then say: ‘This is how it should be for someone who is not in a state of ritual impurity, otherwise he should not to read a single verse of Qur`an.”

If a person reads the Qur`an from memory without touching it, then there is nothing wrong in this case.

God the Almighty knows best.
