What is the ruling on swearing by the right of the Mushaf? And the ruling on drinking and smoking and shisha

Question:
On a Friday, before the preacher ascended the pulpit, I prayed two rak'ahs, and I held the noble Mushaf and said: "By the right of this Qur'an, I will not smoke cigarettes or smoke again for the rest of my life." If I smoke, for example, shisha, have I violated the oath? And do I owe an expiation?

Answer:
It is not permissible for you to swear by the right of the Qur'an. The right of the Qur'an is to magnify it, and magnifying it is among your actions. But if you say "By Allah," or "By the word of Allah," you swear by Allah, or by His word and His attributes, there is no harm. As for by the right of the Qur'an, the right of the Qur'an is that you must magnify it and act upon it, and this is part of your action, and your action is created, so do not swear by created things. But you may swear by the Qur'an itself, by Allah, by the word of Allah, by the knowledge of Allah, by the might of Allah, by Allah or by His attributes, there is no harm.
And you must avoid smoking and all other forbidden things. You must beware of smoking, shisha, intoxicants, and all intoxicating narcotics, even if you have not sworn, and even if you have not taken an oath. It is obligatory for you to avoid them and beware of them; because they are wrong and forbidden, so it is obligatory for you to beware of them and leave them absolutely, even if you have not sworn.
