This work was written to focus in brief on the Pillars of Islam and the articles of Iman (faith). The true believers are:

Those who believe in Allah, His Angels, His Books as Completed by the Quran, His Messengers with Muhammad (Peace be upon Him) being the last of them all.
Those we bear witness that none has the right to be worshiped but Allah and Muhammad (Peace be upon Him) is His Messenger.
Those who observe the five daily prayers.
Those who pay Zakat.
Those who keep the past in the Holy month of Ramadaan.
Those who make the Pilgrimage to the Holy City of Mecca once in a lifetime.
