"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 ﷺ 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.'"  

إِنَّ فُلاَنًا يَقْرَأُ عَلَيْكَ السَّلاَمَ فَقَالَ لَهُ إِنَّهُ بَلَغَنِي أَنَّهُ قَدْ أَحْدَثَ فَإِنْ كَانَ قَدْ أَحْدَثَ فَلاَ تُقْرِئْهُ مِنِّي السَّلاَمَ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ يَكُونُ فِي هَذِهِ الأُمَّةِ أَوْ فِي أُمَّتِي الشَّكُّ مِنْهُ خَسْفٌ أَوْ مَسْخٌ أَوْ قَذْفٌ فِي أَهْلِ الْقَدَرِ  

"There will be a collapse of the earth and transformation in my Ummah, and that is for those who deny Al-Qadar."  

عَنِ النَّبِيِّ ﷺ يَكُونُ فِي أُمَّتِي خَسْفٌ وَمَسْخٌ وَذَلِكَ فِي الْمُكَذِّبِينَ بِالْقَدَرِ
