In the Quraan, Jesus, peace be upon him, says to his people:
“And verily, Allah is my Lord and your Lord.  So worship Him alone.  This is the straight path.”

     (Quraan, 19:36)

"Let whosoever believes in Allah and in the Last Day either speak good or be silent. Let whosoever believes in Allah and in the Last Day honour his neighbour. Let whosoever believes in Allah and in the Last Day honour his guest."

     al-Bukhaari & Muslim
