Shaykh ul Islaam Ibn Taymiyah (Rahimahullaah):

“The perfection of Tawheed is found when there remains nothing in the heart except Allaah, the servant is left loving those He loves and what He loves, hating those He hates and what He hates, showing allegiance to those He has allegiance to, showing enmity to those He shows enmity towards, ordering what He ordered and prohibiting what He prohibits.”


Shaykh Muhammad Saalih Ibnul ‘Uthaymeen:

"So verily the knowledge of tawheed [the oneness of Allaah] is the noblest of sciences, and the greatest in rank, and most obligatory to be studied because it is the knowledge of Allaah the Exalted, and His Names, and His Attributes, and His Rights upon His slaves."



Shaykh ‘Abdul ‘Azeez Ibn ‘Abdullaah Ibn Baaz:

"So this [tawheed] is the most fundamental principle, and the greatest understanding. It is the first thing that the writers should write about, and it is what the callers to guidance, and what the supporters of the truth should focus on. It is the most important science that they should grab onto with their molar teeth, and it should be spread amongst all societies, until they know its reality, and until they distance themselves from whatever opposes it."

The noble scholar Abdur-Rahman Ibn Naasir As-Sa'dee Rahimahullaah, said:

"Know that Tawheed in the unrestricted sense, is the knowledge and the ackowledgement, that the Lord Allaah, is singled out with all the attributes of Perfection. And it is to affir that He is singled out with all the Attributes of Greatness and Majesty. And it is to single Him out alone with all worship..."

Shaykh Muhammad Saalih Ibnul ‘Uthaymeen:

"...So the Prophet, sallaahu 'alayhi wa-sallam, explained the whole of the Religion of Islaam through his sayings , his actions and his tacit approvals, either to begine with, or in response to a question.

And the greatest of all affairs which he made clear (through his sayings, action and tacit approvals), is Tawheed."
