"There will be a collapse of the earth and transformation in my Ummah, and that is for those who deny Al-Qadar."
Jami` at-Tirmidhi Book 32, Hadith 21
← Previous Hadith "So-and-so conveys his Salam to you." So he said: "It has been conveyed to me that he has innovated, so if he has indeed innovated, then do not convey my Salam to him, for I heard the Messenger of Allah (s.a.w) saying: 'In this Ummah' or: 'In my Ummah'" - the doubt was his - "a collapse of the earth, or a transformation, or stones shall rain upon the people of Al-Qadr.'"

Jami` at-Tirmidhi Book 32, Hadith 20 Next Hadith → " Six are cursed, being cursed by Allah and by every Prophet that came: The one who adds to Allah's Book, the one who denies Allah's Qadar, the one who rules with tyranny by which he honors whom Allah has debased, and he dishonors whom Allah has honored, and the one who legalizes what Allah forbade, and the one from my family who legalizes what Allah forbade, and the abandoner of my Sunnah."
