What is the ruling on foul odors from the public road entering rooms containing Quranic verses, when it is impossible to prevent them, and is one sinful if they are able to prevent their entry but do not do so?

Insulting the Qur’an is defined as any statement or action that is customarily considered contemptuous, or that its perpetrator intended to be disdainful. Foul odors coming from a public road are not considered an insult to the Qur’an. As for hanging Qur’anic verses in the home, scholars have differed on this issue.
