When the last moment of the life of Allâh's Messenger (ﷺ) came, he started putting his Khamîsa (a woolen blanket) on his face and when he felt hot and short of breath he took it off his face and said, "May Allâh curse the Jews and Christians, for they build the places of worship at the graves of their Prophet's." [The Prophet (ﷺ) was warning (Muslims) of what those had done]. [1:427-0.B.]
