The Five Roots of Usul al-Din in Shi’a Islam
1 - Tawhid: absolute oneness
2 - Prophethood (Nubuwwah): accepting the truth of Muhammed's prophecies
3 - belief in divine justice (adalat): Allah is just and can do no wrong, humans are accountable to God
4 - the imamate (imamah): accepting doctrine of 12 official leaders (imams) who alone have the right to lead muslims after the death of Muhammed
5 - Belief in the day of Judgement and resurrection: Mi'ad. all will be resurrected after death to be judged by Allah, the good will enter paradise, bad sent to hell
