The 6 pillars of iman (faith) in Islam are:

  1. Belief in Allah (God)
  1. Belief in His angels
  1. Belief in His revealed books
  1. Belief in His messengers
  1. Belief in the Last Day (Day of Judgment)
  1. Belief in divine decree (Qadr) – that all destiny, good and bad, is by Allah’s knowledge and will

These six are mentioned together in the famous hadith about iman, and they form the core creed every Muslim is required to affirm.
