“‘Whoever makes the graves of the prophets and righteous ones into mosques is evil,’ is the title of a seventh-grade textbook.”

This idea isn’t some Wahhabi invention. It comes from statements attributed to Muhammad in the Hadith:

“It was narrated from Aishah that the Prophet said: ‘May Allah curse people who take the graves of their prophets as Masjids [mosques].'” (an-Nasa’i 21.230.2046)

“Narrated Abu Huraira: Allah’s Messenger said, ‘May Allah’s curse be on the Jews for they built the places of worship at the graves of their Prophets.'” (Bukhari 8.86.437)

Nor is it a Wahhabi idea that “the hour will not come until the Muslims fight the Jews and kill them.” That, also, comes from Muhammad:

“Abu Huraira reported Allah’s Messenger as saying: ‘The last hour would not come unless the Muslims will fight against the Jews and the Muslims would kill them until the Jews would hide themselves behind a stone or a tree and a stone or a tree would say: Muslim, or the servant of Allah, there is a Jew behind me; come and kill him; but the tree Gharqad would not say, for it is the tree of the Jews.'” (Muslim 6985)
