How about you ask me those questions. Its about the end of this world . Its a prediction.Sahih al-Bukhari 2926 - Fighting for the Cause of Allah (Jihaad) - كتاب الجهاد والسير - Sunnah.com - Sayings and Teachings of Prophet Muhammad (صلى الله عليه و سلم)
Hadith of the Prophet Muhammad (saws) in English and Arabicsunnah.com
Allah's Messenger (ﷺ) said, "The Hour will not be established until you fight with the Jews, and the stone behind which a Jew will be hiding will say. "O Muslim! There is a Jew hiding behind me, so kill him."
Interpret that in a way that is not vile and barbaric.
Or tell me that Sahih al-Bukhari is not real Islam.
Or tell me that the source I linked to is un-Islamic.
??
Its not mentioned in Quran to fight jews or anything like that.
Secondly there are contradictions in many books of hadiths.
