Why Is Khusūf Called a Calamity in the Words of Imam Sajjad (AS)?
In the words of Imam Sajjad (AS), khusūf means being swallowed up and disappearing. In Supplication 27 of al-Sahifa al-Sajjadiyya, he asks God to destroy and erase the lands of the polytheists. The Quran also conveys this meaning by referring to the people of Lot and Korah being swallowed up by the earth, as well as to the moon’s eclipse on the Day of Resurrection.
