Did Suhail ibn Abi Salih exclusively narrate the hadith found in Sahih Muslim: "Do not greet Jews and Christians first," or was it narrated by others?

The Hadith (definition) "Do not greet the Jews and Christians first" is authentic. Many Hadith Imams have authenticated it, among them Tirmidhi, Baghawi, Tahawi, and Ibn al-Mulaqqin. Its presence in Sahih (definition) Muslim is sufficient proof of its authenticity. Al-Albani also mentioned the consensus of scholars on its authenticity. The variation in its wordings in some narrations has not been considered a flaw in the original Hadith, although this variation might have originated from Suhail bin Abi Salih, who had some weakness in his memory.
