Sleeping with feet pointing toward a book of Quran

It was brought to my attention by a relative that I shouldn't be sleeping with my feet facing towards a quran. I have a bookshelf facing the foot of my bed. Is it a big deal?

As long as the mushaf (book of Quran) is on a shelf then there is no issue. It’s only a problem if it is at the same level as your feet.
