One of customary vows among Muslims is vowing to God, but sending its rewards and benefits to the dead. From jurisprudential perspective, there is no doubt on the legitimacy of this act. But Ibn Taymiyyah did not consider it permissible, having his own reasons. He believes that this kind of vowing and sending the reward to the dead is a kind of polytheism in worshipping. His main reason is some Narration in this field. The writer of this essay with a descriptive analytic method has examined the reasons of Ibn Taymiyyah in detail. According to the findings of this research: the Ibn Taymiyyah's narrations in this filed is problematic in both authenticity of document and denotation.
