It is not permissible to
rent a shop to a person who shaves beards because this will help him continue doing something which is commonly known as prohibited. Allah (Exalted be He) says:
Help you one another in Al-Birr and At-Taqwâ (virtue, righteousness and piety); but do not help one another in sin and transgression.
