Whoever disbelieves in Taghoot and believes in Allaah, then he has grasped the most trustworthy handhold that will never break. And Allaah is All-Hearer, All-Knower
} [Al Al Baqarah: 256]
This Ayah is the best explanation for the statement of Tawheed, you will not find a clearer explanation than this Ayah for ‘there is no deity worthy of worship in truth except Allaah’ in relation to method.
You will find that disbelief was mentioned before Eemaan. One must firstly disbelieve in Taghoot, if a person were to have Eemaan that Allaah is One and does not perform worship to other than Allaah, but does not disbelieve in at Taghoot in any of the types of worship, whether in worship such as Du’aa, Isti’aanah, Nadhr, or in judgement [it would not benefit him]. So if a servant singles out Allaah in the Tawheed of worship, he does not perform worship to other than Allaah, but does not single Allaah out in judgment, the Tawheed of Worship would not be accepted from him.
Rather one must disbelieve in Taghoot in a comprehensive manner in all affairs, and have Eemaan in Allaah in a complete manner that is not segmented. Whoever believes in Allaah alone, does not practice Istighaathah to other than Allaah, does not supplicate to other than Allaah, he slaughters for Allaah alone and draws closer to Him with the known forms of worship, but if that person turns to Taghoot for judgment, this would not benefit him.
For Eemaan, one has to disbelieve in Taghoot in all affairs, meaning whoever seeks judgment form other than what Allaah has revealed, the Tawheed of Worship would not benefit him. Rather one must disbelieve in Taghoot in all affairs.
This is what is meant by ‘Tawheed revolves around negation and affirmation’ rather it revolves around Kufr and Eemaan. One must combine between Kufr and Eemaan as is evident in the Ayah, as well as your declaration: ‘I bear witness that there is no deity worthy of worship in truth other than Allaah, and that Muhammad is His messenger.’
This negation and affirmation is not restricted to only the first clause of the statement [of the Shahaadah], rather it is included in the second clause as well; ‘Muhammad is His messenger’. This is done by only following and obeying the Messenger of Allaah - عليه الصلاة والسلام. The Messenger of Allaah has unrestricted obedience, it is not restricted. Just as Allaah’s obedience is unrestricted, likewise the Messenger’s obedience is unrestricted - عليه الصلاة والسلام. This is an important issue that the student of knowledge must understand, that the obedience of the Messenger is unrestricted.
 The Shaykh’s comments must be understood in light of his other explanations where he comments on the issue of ruling by other than what Allaah has revealed in detail. The Shaykh may Allaah have mercy upon him was at the forefront of refuting those who declare rulers as disbelievers or consider judging by other than what Allaah has revealed as disbelief unrestrictedly. His detailed comments on the topic will be linked to this article in the future inshaa-Allaah.
