Someone said to him, "So-and-so sends his greetings of peace to you."He replied, "It has reached me that he has introduced an innovation. If he has indeed done so, then do not convey my greetings to him, for I heard the Messenger of Allah ﷺ say, 'There will occur in my nation,' or he said, 'in this nation, transformations, swallowings of the earth, and showers of stones, and that will befall the people who deny divine decree.'"
