Sayyiduna Shaddad (may Allah be pleased with him) narrates: I came to the Prophet (peace and blessings be upon him) and took hold of his (peace and blessings be upon him) hand, and it was softer than silk and cooler than snow.
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat. The narrators of al-Mu'jam al-Kabir are the narrators of the "Sahih", except for Musa bin Ayyub al-Nasibi, and he is thiqah (trustworthy).
