In Islam, there is a belief in the oneness of God (Allah) who is both transcendent and immanent. The core tenets include the Five Pillars of Islam, which are:
1. **Shahada (Faith)**: Declaring the oneness of God and the finality of the prophethood of Muhammad.
2. **Salah (Prayer)**: Performing the five daily prayers.
3. **Zakat (Charity)**: Giving to those in need and helping to purify wealth.
4. **Sawm (Fasting)**: Observing fasting during the month of Ramadan.
5. **Hajj (Pilgrimage)**: Undertaking a pilgrimage to Mecca at least once in a lifetime, if financially and physically able.
The teachings of Islam are based on the Qur'an, considered the literal word of God as revealed to Muhammad, and the Hadith, which are the sayings and actions of the Prophet Muhammad. Muslims aim to live a life in accordance with these teachings, focusing on worship, morality, and compassion.
