In the name of Allah, the Most Merciful, the Most Compassionate
1. Associating partners with Allah (shirk). Allah Most High says (in the meaning ): “Truly, whosoever sets up partners with Allah, then Allah has forbidden the Garden for him, and the Fire will be his abode. And for the wrongdoers there are no helpers.” (Soorah Al-Maaida 5:72) Calling upon the dead, asking their help, or offering them gifts or sacrifices are all forms of shirk.
