Tawheed
There is none worthy of worship except Allah
The Holy Quran
In the name of Allah, the Gracious, the Merciful.
Say, ‘He is Allah, the One;
Allah, the Independent and Besought of all.
He begets not, nor is He begotten;
And there is none like unto Him.’ (Holy Quran, Chapter 112)
Ahadith (Sayings of Prophet Muhammadsa)
When the Prophet sent Muadh to Yemen, he said to him, “You are going to a nation from the people of the Scripture, so let the first thing to which you will invite them, be the Tauhid of Allah. If they learn that, tell them that Allah has enjoined on them, five prayers to be offered in one day and one night. And if they pray, tell them that Allah has enjoined on them Zakat of their properties and it is to be taken from the rich among them and given to the poor. And if they agree to that, then take from them Zakat but avoid the best property of the people.” (Sahih Bukhari, Volume 9, Book 93, Number 469)
The Promised Messiahas
But, first and foremost, I have been sent to re-establish forever the lost belief in the Unity of God—Tauhid—which is pure and luminous and unadulterated by any form of idolatry—Shirk. (Lecture Lahore, 2008 Edition, p. 42)
