The Messenger of Allah ﷺ said, "The Hour will not come until thirty liars appear, men every one of whom lies about Allah and His Messenger ﷺ."
وقال رسول الله ﷺ لا تقوم الساعة حتى يخرج ثلاثون كذابا رجالا كلهم يكذب على الله عز وجل ورسوله ﷺ
Its isnad is sahih, for the same reason as the previous one, which has already been mentioned. It was also reported by Abu Dawud 4334, and Tirmidhi 2218.
