A Critical Assessment of the Traditions of the Descent of the Quran on the Sahābah's Tongues (A Look at the Book of Al-Itqān by al-Sūyūti)

One of the most important sources in the field of the Quranic sciences is Jalāl al-Dīn al-Sūyūti's al-Itqān Fi Ulūm al-Quran that has drawn the attention of Quranic scholars and researchers from various aspects.
This work, like any other works, is not immune from defects and errors which have found their ways into it. Due to its relevance to Quranic sciences, closing eyes to the above objections will have far-reaching consequences.
Therefore, in this research, which is carried out on library and content based analytical method; we would study and criticize one of the controversial issues existing in this work.
The tenth section of al-Itqān titled. "Fima unzil min al-Qurān ala lisān baz as-Sahābah" claims a kind of pre-revelation or inspiration of some verses of the Holy Quran on the tongue of the Prophet's companions. Whether or not the claim is genuine, the assessment reveals that the purport of these reports is in utter contrast with the indisputable rational, historical and narrative proofs.
