Chautha Kalima The Fourth Kalima Tawheed means the Word of Oneness or Unity The word “Tauheed” means to “accept the oneness of Allah”. In Islam, the Tauheed reflects the concept of monotheism for Allah which means that the Muslims assert that there is no God but Allah and to Him, they shall return. Tauheed is the first pillar of Islam which along with other pillars completes the cycle of faith in a Muslim’s life. The acceptance of Tauheed is the major difference between the Muslim and a Non-Muslim. The fourth kalima is also referred to as Tauheed or Tawheed meaning ‘unification of oneness of God’. This is the first pillar which is the central doctrine in Islam. It holds that Allah is One (Al-Ahad) and Single (Al-Wahid). In the Qur’an one of the worse sins you can commit is shirk, which refers to associating partners or to accept other divinities alongside Allah. Shirk is a serious sin and according to Qur’an is unforgivable.
