This was fascinating and exciting to read. I know there are shaykhs still alive who have a sanad (chain of authority) back to the Prophet salallahu alayhi wasalam and shake hands with people, in the EXACT same manner as the Prophet salallahu alayhi wasalam did. This is yet another reason why Islam cannot be reduced to books or copy-paste fatwas, one needs to learn from a REAL shaykh who has ijazas and understands the true spirit of Islam- to carry the same attitude towards Islam as the Prophet salallahu alayhi wasalam did- in the most preserved manner. I only found out about this after meeting someone who is part of this sanad.
In the hadith literature there is a category called musalsal (continuous). A musalsal hadith is such that all its narrations over the centuries shared a common attribute. Some of these ahadith include gestures. For example Anas, may Allah be pleased with him, reported a hadith about the hand-shake of the Prophet, Sall-Allahu alayhi wa sallam,, Allah’s blessings and peace on him. “Prophet, Sall-Allahu alayhi wa sallam’s hand was softer than silk,” he reported. But the report was accompanied by an actual hand-shake, just like the original. There are people living today who have received this hadith, along with the hand-shake, through an unbroken chain that goes back to the Prophet, Sall-Allahu alayhi wa sallam. This is hadith musalsal bil masafaha (continuous with hand shake).
