What is the Islamic ruling on one who says that Buddha was a Prophet?.
Praise be to Allaah.
Buddha was not a Prophet, rather he was a kaafir philosopher
who followed a religion that was not divinely-revealed. Whoever believes
that he was a Prophet is a kaafir. His people exaggerated about him and
believed that he was divine, and they worshipped him instead of Allaah. This
idolatrous Buddhist religion was adopted by many people in the past and in
modern times. The Muslim is obliged to dismiss this religion and its
followers, and to disavow himself of it and take a stand against them for
the sake of Allaah.
And Allaah is the Source of strength. May Allaah send
blessings and peace upon our Prophet Muhammad and his family and companions.
