(Fatwa: 676/671=M)
(1) In this case, in your work include only cleaning the floor and placing the thing including alcohol to proper place then it is allowed; since these actions involve no sin, such instances are found in the books of scholars of Fiqh:
و جاز تعمیر کنیسۃ و قال ابن عابدین قولہ جاز تعمیر کنیسۃ قال فی الخانیۃ: و لو آجر نفسہ لیعمل فی الکنیسۃ و یعمرھا لا بأس بہ لأنہ لا معصیۃ فی نفس العمل
(2) It is unlawful to touch pork to make pizza; since it is helping in sin and polluting yourself with impure thing; therefore it is not right for you to work in a pizza hut.
