This is not “extremist” Islam. This is the standard, mainstream religion. It’s a hadith in a collection that Muslims consider authentic:
“Abu Huraira reported Allah’s Messenger (may peace be upon him) 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.” (Sahih Muslim 6985)
Muslims in Texas don’t have a different version of Islamic texts and teachings from the version Muslims have elsewhere. They have the same Qur’an, the same Sunnah. Why should anyone expect them not to teach the things these sources say?
But what are American authorities going to do when they realize this is not twisted, hijacked Islam, but orthodox Islam? Or will it be too late by then?
“Houston Imam Raed Saleh Al-Rousan: ‘Good Tidings’ – Muslims Will Kill Jews On Judgment Day; ‘Do Not Tell Me That Palestine Is The Country Of The Jewish [People],'” MEMRI, December 8, 2017:
In his Friday, December 8, 2017 sermon titled “Our Duties Towards Al-Quds [Jerusalem]” at the Tajweed Institute’s Houston, Texas branch, the institute’s imam and founder Sheikh Raed Saleh Al-Rousan focused on U.S. President Trump’s December 6 Jerusalem declaration, said, speaking in a combination of Arabic and English, that the Jews “killed the Prophets and the Messengers of Allah” and went on to cite the widely quoted Hadith stating that on Judgment Day, the Muslims will kill the Jews: “My brothers, the Prophet Muhammad brought the good tidings, when he said: ‘Judgment Day will not come until the Muslims fight the Jews. The Muslims will kill the Jews, and the Jews will hide behind the stones and the trees, [which] will say: Oh Muslim, oh servant of Allah, there is a Jew hiding behind me, come and kill him… This is the promise of Allah.” He added: “The hour [i.e. Judgment Day] will not start until Muslims fight the Jews there, in Palestine.” He also said that since “Britain brought Jewish [people] from different countries to live in Palestine… do not tell me that Palestine is the country of the Jewish [people].” The Tajweed Institute was founded in Florida by Sheikh Al-Rousan in 2013, and the Houston branch was opened in mid-2017. The video of the sermon was posted by the Tajweed Institute on its Facebook and YouTube accounts.
