Day of Judgment (Yawm al-Qiyama) is one of the six pillars of Islam (Rukn al-Iman). No one, not even a prophet, nor a prophet, can know the exact time of the Day of Judgment, except by Allah alone. However, the Prophet Muhammad (peace and blessings of Allaah be upon him) described the proclamations (Ashrat al-Sa'ah) so that His people would be awakened, prepared, and clinging to good deeds. These signs are divided into two major types: Minor Signs and Major Signs.
