The Prophet Muhammad (saas), who reminded his people that Allah was one God, also conveyed in various ways that none of the things which they ascribed as partners to Allah, would harm anyone or do any good. Some of the relevant verses are as follows:

Say: “Pray if you will to those whom you deify besides Him. They cannot relieve your distress nor can they change it.” (Surat al-Isra’, 56)

Say: “Have you pondered on those you invoke besides Allah? Show me what part of the Earth they have created. Or do they have a share in the heavens? Produce a Book for me revealed before this one or some other shred of divine knowledge, if you are telling the truth.” (Surat al-Ahqaf, 4)

Say: “Call on those whom you deify besides Allah. They have no power over even the smallest particle, either in the heavens or on Earth. They have no share in them. Nor has He any helpers among them.” (Surah Saba’, 22)

Say: “Show me those you have appointed to Him as associates. No indeed! Allah alone is the Almighty, the All-Wise.” (Surah Saba’, 27)

Say: “Have you seen your partner gods, those you call upon besides Allah? Show me what part of the Earth they have created, or do they have a share in the heavens?" Have We given them a Book whose Clear Signs they follow? No indeed! The wrongdoers promise each other nothing but delusion. (Surah Fatir, 40)
