Assalamu alaykum, I was wondering if hookah or sheesha is permissible?

The youth here are very much into it and I was looking for some advice from the basis of Quran and Sunnah. 

Jazak Allah khayr

Wa Salaam

In the name of Allah, the Most Merciful, the Grantor of Mercy

All praise belongs to Allah, and may prayers and peace be upon Allah’s final Messenger.

Smoking and using all kinds of tobacco in any form is forbidden (haram). This ruling is because there is a total consensus among sensible people on its harms and evils. The Messenger of Allah (pbuh) said: "There should be neither harm nor reciprocation of harm."

There used to be some controversy surrounding the harms of smoking in the past, resulting in some earlier scholars in the beginning of the twentieth century hesitating to forbid it. But now, there is no more controversy at all about its harms, and consequently, the ruling of its prohibition is established and confirmed.

It is also wasteful, and those who use tobacco waste their money on something that will bring disease and harm to their bodies. Allah said:  "Surely the squanderers are the fellows of the devils and the Shaitan is ever ungrateful to his Lord." (al-Isrā' 17:27)

[Reviewer’s note: There is, however, some difference of opinion among scholars on whether it is permissible for a person who did not know about its harms to continue smoking/using tobacco after they learned that it is harmful. It is the position of the AMJA Resident Fatwa Committee that it is impermissible to continue.]

Allah knows best.
