All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Sheeshah is forbidden; it is neither permissible for a person to consume it nor to serve it.
Since this profession requires serving it, then it is not permissible for you to work in it unless you are poor and needy and you do not find a permissible work from which you can earn your necessary spending and that of those whom you are obligated to provide for and spend on. In this case only are you permitted to remain in this job until you find another permissible one, and it is an obligation on you to endeavor to find one. Indeed, necessity is valued according to its proper value.
For more benefit on the necessity that makes what is forbidden permissible, please refer to Fataawa 237190, 21302, and 90215.
For more benefit on the ruling on Hubble bubble (Sheeshah), please refer to Fataawa 144529, and 285196.
For more benefit on the prohibition of smoking, please refer to Fataawa 354349, 282784, 81933, and 85441.
Allah Knows best.
