There are Ahadith which say so. They first met each other outside the Kaba many years before Muhammad (saaw) received revelation, where Waraqa kissed Muhammad’s head, the next time they met was after Gabriel spoke to Muhammad (saaw) in the cave, and Waraqa died soon after.
I think you’ve got your chronology quite confused, Muhammad’s revelations didn’t die out after Waraqa’s death, they’d only just begun. The only verses that had been revealed at this time were the first five verses of Sura Al-Alaq (which has nothing to do with Jesus (as)).
[quote=QuietTimes]You are right they hold very different beliefs, but none the less they both hold wrong views of Christ.
Because they both have differing views of Christ to Catholicism is hardly a good argument to claim one influenced the other, especially since as you note they are themselves very different.
