Shisha is a smoking device comprising of a hard body, a water pipe, hose and clay pot, where the substance burnt is a mix of tobacco, honey and fruit flavouring.
According to research result issued by the Unit, 45 minutes of shisha smoking is equivalent to smoking 50 tobacco cigarettes.

Islam scholars (Hadith&Quran) says..
Accordingly, the Holy Quran says “and make not your own hands contribute to your destruction, but do good. For Allah love those who do good,”(2:195).
In another Aayat, Allah Ta'ala says, 'And do not kill yourselves'. (Nisaa
29). Nabi Sallallaahu Alayhi Wasallam said, 'Whomsoever drinks poison,
thereby killing himself, will sip this poison forever and ever in the fire
of Jahannum.'
Shari'ah has explained in great length the
importance and virtue of good health to the extent that Rasulullah
(Sallallaahu Alayhi Wasallam) even advised to maintain a balance in eating
and drinking as an imbalance could be harmful to health. He advised having
dates, being hot in nature with cucumber, as it (cucumber) has a cooling
effect. (Shamaail). On one occasion, Rasulullah (Sallallaahu Alayhi
Wasallam) even stopped Hadhrat Ali (Radhiallaahu Anhu) from eating dates
upon recovering from his illness and advised him to have vegetables instead.
Although dates is not only nutritious but also a means of obtaining
blessing, but in certain conditions, since it could be harmful, Rasulullah
(Sallallaahu Alayhi Wasallam) advised against it. From that, one can gauge
the extent of abstaining from cigarettes which contain many harmful
ingredients, for example, carbon monoxide, nicotine, tar and benzene vapour
Smoking did not exist in the time of Rasulullah (Sallallaahu Álayhi
Wasallam), but our magnificent Deen has laid down general principles from
which many laws are derived. From these principles, the Ulama (Allah's mercy
be upon them) have come to the conclusion that smoking is Haraam.
