الحمد لله رب العالمين، وصلى الله وسلم على نبينا محمد وعلى آله وأصحابه أجمعين، أما بعد
Al-‘Allaamah Ibn Qayyim Al-Jawziyyah (rahimahullaah) said:
“For indeed; every aayah in the Qur’aan – then it comprises of Tawheed, as an attestation of it – a caller to it. Indeed; the Qur’aan is:
- Either information (news) regarding Allaah, and of His Names and His Attributes and His Actions, so it is: the Tawheed of knowledge and that which is informative (regarding Him) (at-Tawheed al-‘Ilmee al-Khabaree).
- Or either it is a call to worship Him alone – and not attributing any partners to Him, as well as to reject everything that is worshipped besides Him. So it is Tawheed of intention and pursuant action (at-Tawheed al-Iraadee at-Talabee).
- Or either it is command and prohibition, and a requisite of having obedience to Him in His prohibitions and His commands. So it is the rights of Tawheed and a completion of it.
- Or either it is information regarding the dignified esteem of the people of His Tawheed – and obedience to Him; and that which occurred with them in the life of this world – as well as that which they will be ennobled with in the Hereafter. So it is the reward of having Tawheed with regard to Him.
- Or either it is information regarding the people of shirk and that which occurred with them in the life of this world by way of exemplary punishment, as well as that which will descend upon them in the retribution by way of punishment (in the Hereafter). So it is information concerning the one that exited from the ruling of Tawheed.
Hence; the Qur’aan – all of it is in relation to Tawheed and of its rights and its reward, as well as of the affair of shirk; and its people; and their recompense.”
Al-‘Allaamah ‘Abdur-Rahmaan bin Hasan Aal Ash-Shaikh (rahimahullaah) said:
“Whoever reflects upon the Qur’aan – desiring to follow a right way, whilst listening; and is attentive, then he comes to know that the Messengers were indeed sent to the people with the call: that they should act in accordance to Tawheed. As well as to carry out that which Allaah made obligatory upon them and to avoid that which He prohibited them against – from worshipping other than Him, and to make their actions sincere for Allaah – alone.
The Glorious Qur’aan; from its beginning to its end; it stipulates this very Tawheed, and prohibits making shirk (associating partners) with Allaah in worship of Him – which by way of that the intending of other than Him is improper.
So look; and listen – you will find it stipulating sincerity and its legislations, as well as rejecting shirk and all that entails it – in the clearest declaration. Likewise the ahaadeeth and biographic accounts rightly guide to that, and so they consolidate it in the most complete aspects and in the finest declaration.”
Al-‘Allaamah ‘Abdur-Rahmaan As-Sa’dee (rahimahullaah) said:
“And from the perfect completeness of the Qur’aan is that is calls to the Tawheed of Allaah and of having an understanding of Him, through the mention of the Names of Allaah and His Attributes and His Actions which prove His uniqueness in singularity by way of (His) Oneness. As well as the Attributes of perfection, and that He is The Truth and worship of Him is true, and that which they call upon other than Him; then it is falsehood. It makes clear the deficiency of everything that is worshipped besides Allaah – from every aspect.”
 Shaikh Saalih Al-Fawzaan (hafidhahullaah) mentions in his Duroos min Al-Qur’aan (p.1) in explanation of this term as stated by Ibn Al-Qayyim, that it is the information regarding Allaah and of His Names and Attributes, and that this is Tawheed al-‘Ilmee which is: Tawheed ar-Ruboobiyyah.
Al-Haafidh Al-Hakami (rahimahullaah) said: “Tawheed al-‘Ilmee al-Khabari al-I’tiqaadi – comprises of an affirmation of the Attributes of Perfection for Allaah, The Mighty and Majestic, as well as declaring Him free in that from making any resemblance and likening (unto Him) and declaring Him free of the attributes of deficiency. So it is Tawheed Ar-Rububiyyah and Tawheed al-Asmaa wa Sifaat.” (See: Ma’aarij al-Qubool vol 1 p.98)
 Shaikh Saalih Al-Fawzaan (hafidhahullaah) mentions in his Duroos min Al-Qur’aan (p.1) in explanation of this term, that it is the command to worship Allaah alone, and not to associate any partners with Him and a forbiddance from shirk, and that this is Tawheed al-‘Amalee at-Talabee which is: Tawheed al-Uloohiyyah.
Al-Haafidh Al-Hakami (rahimahullaah) said: “Tawheed at-Talabi al-Qasdi al-Iraadi – and it is the worship of Allaah, The Most High – alone – without there being any partners for Him, as well as exclusively having love of Him and having sincerity for Him and fearing Him and hoping in Him and having trust/reliance upon Him and being pleased with Him as a Lord and Diety and Protector. Likewise that one does not make an equal for Him in anything; and it is Tawheed al-Uloohiyyah.” (See: Ma’aarij al-Qubool vol 1 p.98)
