“And most certainly We gave Musa the Book, but differences arose therein”
Imam Baqir (as) said, They differed (about the Book) just like this nation has differed about the Book. They will differ (again) about the Book which is with the Qaem (as), which he will bring for them. Many people will refuse it, so the Qaem (as) will kill them. (Al Kafi volume 8 page 287)
