It is impermissible to
rent a shop to a person who sells musical instruments and tapes, because this is considered cooperation in prohibited things and promotion of falsehood, as 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.
