The ruling on kissing the Mus-haf
Q: What is the ruling on kissing the Mus-haf (Arabic Qur’an) if it falls from an elevated place?
A: There is no evidence on the prescription of kissing the Mus-haf. However, there is no harm in doing this, as it was narrated on the authority of the great Sahaby (Companion of the Prophet) `Ikrimah ibn Abu Jahl (may Allah be pleased with him) that he used to kiss the Mus-haf and say, “These are my Lord’s Words.” Anyhow, there is no harm in kissing the Mus-haf, but there is no evidence on its prescription.

If a person kisses it out of honor and respect when it falls from an elevated place, there is no harm in this in sha’a-Allah (if Allah wills).
