Evaluation of traditions signifying that the Prophet (S) shook

In this research the traditions are classified in four groups: 1) verbal allegiance along with bodily action, 2) bodily action, 3) verbal allegiance, 4) permissibility of shaking non-mahram women (or men) by the hand under the condition of existence of a cover (e.g. gloves, etc. as an impediment to direct touch).
By studying the content of those traditions it is concluded that many of (seemingly) contradictory traditions are indeed complements to one another and can be brought together. Only those traditions are unacceptable that denote permissibility of shaking hands (with a non-mahram) without there be an impediment to direct touch. In addition, the effects of the verse (Q 60:12) on these traditions become clear, because on the one hand the atmosphere of paying allegiance to the Prophet (S) by the women is elucidated by different groups of traditions, and on the other hand the authenticity of the related traditions can be examined by studying the cause of revelation of this verse.
