Yousof Haddad Doubt regarding Verse 94 of Chapter Younus and its Critique

Yousof Haddad regarding verse 94 of chapter Younos has claimed that Prophet Mohammad usually referred to the ahl al-Ketab for removing his doubts. This research via descriptive – analytical method has shown that Prophet Mohammad never doubted in his mission, so that he needed to refer to the ahl al-Ketab. Hence, his claim has five impediments. A. This issue is incompatible with the context of the Quran verses, challenge verses, and the sprit of the Quran; B. The narrations related to this verse do not prove the claim. C. this verse is similar to the proverb: "He told to the door so that the wall hears"; moreover, there are many samples in the Quran like this verse; D. the word "Åä" does not imply on the necessity of occurrence. E. if we accept the implication of verse on doubt, others are more likely to be skeptical than the prophet.
