What is the ruling on working in painting and decorating a shop that sells alcoholic beverages, and working as a secretary for a psychotherapist who uses meditation and relaxation in her treatment?

Your sister's husband must leave his job in the shop's construction if he knows that alcohol or other forbidden things will be served there, in compliance with Allah's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." As for the second question, it must be noted that there are healing methods derived from pagan Eastern origins, such as energy healing, yoga, relaxation, and meditation. To understand the truth of this, it is recommended to consult the books of Dr. Fawz Bint Abd Al-Latif Kurdi and her website.
