The world will come to an end on the Day of the Resurrection (Qiyāmah), the Day of Judgement. All will be resurrected and presented before God who will decide their individual fates according to their beliefs and deeds in this world. Good will be rewarded and evil be punished (22:1, 2 & 6-9; 3:185; 6:62). God will treat people with justice but the dominant factor in the administration of His Justice will be His Mercy (6:12).
Although all Muslims believe in the above principles of Islam, there is a slight difference in their articulation of these beliefs and practices. Shi‘a Muslims express the above beliefs as principles or roots of the religion (Usūl al-Dīn) and the acts of worship to follow as practices or branches of the religion (Furū‘ al-Dīn). The reason for such an articulation is that those beliefs are the most fundamental aspects of the religion and the criteria for being considered a Muslim. However, the mandatory acts of worship are implications of being faithful, since genuine faith manifests itself in practices. Sunni Muslims usually present the declaration of Islam (kalimah) consisting of bearing witness that there is no god but God (Allah) and that Muhammad is His Messenger together with four acts of worship, i.e. the daily prayer, fasting, pilgrimage to Mecca and almsgiving as the Five Pillars of Faith. They consider other acts of worship such as enjoining good and forbidding evil, and struggle in the way of God as obligatory acts that are not included amongst the Pillars of Faith.
