I heard the Messenger of Allah ﷺ say, "Do not exalt me excessively as the Christians exalted the son of Mary. I am only His servant, so say, 'the servant of Allah and His Messenger.'"
سمعت رسول الله ﷺ يقول: لا تطروني كما أطرت النصارى ابن مريم، فإنما أنا عبده، فقولوا: عبد الله ورسوله.
Bukhari narrated it in the Chapters on the Prophets (3445), from Humaydi, who said, Sufyan narrated to us, saying, I heard Zuhri say, Ubaydullah bin Abdullah informed me, from Ibn Abbas, who heard Umar say on the pulpit, and he mentioned the hadith.
