What is the ruling on erasing Quranic text written on a board used for teaching at university?

The Quran is the speech of Allah Almighty and must be treated with reverence. Accordingly, jurists have maintained that it is forbidden for a person in a state of minor or major ritual impurity, a menstruating woman, or a woman experiencing postnatal bleeding, to touch a physical copy of the Quran or any Quranic text written on a tablet, wall, or currency. However, children are exempt from this ruling and are permitted to touch a physical copy of the Quran or write Quranic verses on a tablet when necessary, such as when memorizing the Quran, because what is memorized during childhood is more firmly retained, whereas postponing it until adulthood may result in a diminished capacity for memorization.

Hanafi jurists have also maintained that it is permissible to erase the Name of Allah Almighty or any Quranic text written on a sheet of paper, provided that saliva is not used. They likewise held that it is permissible to erase a tablet on which Quranic text have been written.

 

The ruling

Based on the above, it is permissible to erase any Quranic text written on the main board of a lecture hall to continue using the board for teaching, provided that saliva is not used. This is permitted out of necessity and to prevent those in a state of minor or major ritual impurity from touching the Quranic text written on the board and thereby committing a sin.

And Allah Almighty knows best.
