In the name of Allah, We praise Him, seek His help and ask for His forgiveness. Whoever Allah guides none can misguide, and whoever He allows to fall astray, none can guide them aright. We bear witness that there is none worthy of worship but Allah Alone, and we bear witness that Muhammad (saws) is His slave-servant and the seal of His Messengers.
Allah Says in the Holy Quran Chapter 56 Surah Waqiah verses 77-79
77Â Â Â Â Â Â That this is indeed a Qur’an, most honorable
78Â Â Â Â Â Â In a Book well-guarded
79Â Â Â Â Â Â Which none shall touch but those who are clean:
Although the above aayah is meant to state how the Quran is honored by the noble Angels in the heavens;  the scholars have opined that just as the Quran is honored in the heavens by the Angels,  so should it be honored by the believers on the earth…. And thus, one, who sincerely believes in Allah and the Last Day, should touch the Glorious Quran only when one is pure and clean, and preferably when in the state of wudu.
The majority of the scholars are of the opinion that there is absolutely no requirement of wudu if one recites the Glorious Quran from one’s memory; but it would be preferred (not an obligation nor a requirement) that one be in the state of wudu when reciting the Quran whilst looking or holding a copy of the Glorious Book.
Whatever written of Truth and benefit is only due to Allah’s Assistance and Guidance, and whatever of error is of me alone.  Allah Alone Knows Best and He is the Only Source of Strength.
