A study on traditions in Shia and Sunni sources denoting that the Prophet and the Pure Imams had no shadows

In certain Shia and Sunni hadith books some traditions are found denoting that the Prophet (s.a.w) and the Infallible Imams (a.s) had no shadows. The traditionists and writers that have recognized these traditions, maintained this characteristic as a miracle for the sacred pure Infallibles; however, on the contrary most of the thinkers either kept silent and adopted no stance) when they faced such traditions or did not cite them in their books to imply their weakness (in their opinion). In a broad outline most of these traditions suffer from weakness in their chains of transmission (isnads). In other words, their isnads suffer from the defect of infirād, and do not contain trustworthy transmitters, as well. Moreover, their texts seem to be unacceptable when they are criticized, or presented to the Quran. Unconditional acceptance of these traditions paves the way for the extravagant and extremist claims about the Infallibles. In addition, it gives the opponents pretext to mention sarcasms against the Shia.
