The five roots of Usul ad-Din Revision Notes

Tawhid is the foundational belief in Islam that God is one, unique, and indivisible. This principle rejects any form of polytheism or association of partners with God. It establishes monotheism as central to Muslim faith and worship.

Understanding Tawhid shapes how Muslims relate to God, emphasising direct worship without intermediaries. For example, a Muslim praying five times a day focuses solely on God’s singularity and sovereignty.

Tawhid influences ethical behaviour by reminding believers that God alone is the ultimate authority and judge, encouraging sincerity and devotion in all actions.

• God is singular and unique, without partners or equals.
• Forms the basis of all Islamic beliefs and practices.
• Encourages direct relationship and worship of God.

ʿAdl refers to the belief that God is just and fair in all actions and decisions. This principle assures believers that God’s justice governs the universe and human affairs.

It implies that suffering and evil have a purpose within divine wisdom, and that ultimate justice will be served, especially on the Day of Resurrection.

For example, a Muslim may find comfort in ʿAdl when facing hardship, trusting that God will reward patience and punish wrongdoing fairly.

• God’s justice is perfect and absolute.
• Encourages moral responsibility and trust in divine fairness.
• Provides hope for ultimate justice beyond this life.

Risalah means the belief that God sends prophets to guide humanity by conveying His message and laws.

Prophets, including Muhammad as the final prophet, serve as examples of ideal behaviour and intermediaries who explain God’s will.

This principle influences Muslims to follow prophetic teachings and the Quran as guidance for life. For instance, Muslims emulate the Prophet Muhammad’s honesty and compassion in daily interactions.

• Prophets communicate God’s guidance to humans.
• Muhammad is the final prophet in Islam.
• Following prophetic teachings is essential for correct belief and practice.

Imamah is a distinctive Shia belief that God appoints specific leaders, the imams, to guide the Muslim community after the Prophet Muhammad.

Imams are considered infallible and divinely chosen to interpret scripture and lead both spiritually and politically.

This principle affects Shia Muslims’ religious practices and community structure, as they seek guidance from the imams’ teachings and example. For example, Shia Muslims commemorate the martyrdom of Imam Husayn to reinforce loyalty and justice.

• Imams are divinely appointed leaders after the Prophet.
• They provide authoritative interpretation of Islam.
• Central to Shia identity and religious life.

Miʿad is the belief in a final Day of Resurrection when all humans will be raised and judged by God based on their deeds.

This principle motivates ethical behaviour, as Muslims anticipate accountability and reward or punishment in the afterlife.

For example, the awareness of Miʿad encourages Muslims to perform good deeds and avoid sin, knowing their actions have eternal consequences.

• Belief in resurrection and final judgment.
• Encourages moral responsibility and hope for reward.
• Shapes attitudes towards life and death.
