Is it permissible to use the wooden Qur'an stand to place other books on it, such as heavy scientific books, for the purpose of studying and alleviating the hardship of sitting?

We thank the questioner for her interest in respecting the Holy Quran, for glorifying the rituals of Allah is best for a Muslim. It is permissible to use the stand designated for the Mushaf to place another book upon it, as this does not contradict the veneration and respect of the Mushaf.
