It is narrated from Hazrat Ubayy bin Ka'b (may Allah be pleased with him) regarding the interpretation of this command of Allah Almighty: "And He is able to send upon you..." that these are four things, and all four are punishments, and all of them will certainly occur. Thus, two of them occurred only twenty-five years after the passing of the Noble Prophet (peace and blessings be upon him): the Muslims were divided into different sects and began to taste the bitterness of fighting one another. And two remain, which will certainly take place: the swallowing up by the earth and the raining of stones from the sky.
