Tawhid means oneness, more broadly referring to the Oneness of Allah.
Tawhid is to recognize and have conviction in the belief that Allah is
One’ and no other is His partner in His Being and in His divine Attributes and Works.
This belief in Tawhid is the foundation of Islamic Din (way of life). It is the first of the five pillars of Islam and of iman (faith). Chapter 112 of the holy Qur’an (Surah Ikhlas) most precisely embodies the explanation of Tawhid‐e‐Ilahi.
A Muslim (follower of Islam) is one who believes that there is no illah (deity) except Allah; that no one except Allah is worthy of worship; does not attribute a partner to Him, in any way or of any sort, and believes that no one is Allah’s son or daughter. This is absolutely fundamental to being a Muslim and anyone who rejects this is not a believer. A Muslim, in his/her right mind, cannot commit shirk (polytheism). Any expression of shirk is directly against the belief of Tawhid.
Nowadays, it is necessary for Muslims to know the true definition of Tawhid so no one can misguide them by labeling them or any other Muslim with shirk, rendering them a mushrik (one who attributes partners to Allah.)
