توحيدالآسمأوالصفات : Allah (swt) described Himself with beautiful Names and Attributes. These attributes are unique to Him. And no one is similar to Him in anyways. He (swt) is not like anything that the mind can imagine. Allah (swt) said: لَيْسَ كَمِثْلِهِ شَيْءٌ “There is nothing like Him”. This is usually referred to as توحيدالآسمأوالصفات (Tawheed-u-Asma-wa-Sifaat)
This category of Tawheed deals with Names and Attributes of Allah (swt). All the names and attributes that belong to Allah (swt) are told to us by Allah (swt) in the Quran. The Tawheed of Allah in His Names requires that we believe in each and every name that He (swt) ascribed to Himself.
وَلِلّهِ الأَسْمَاء الْحُسْنَى فَادْعُوهُ بِهَا وَذَرُواْ الَّذِينَ يُلْحِدُونَ فِي أَسْمَآئِهِ
7.180 And (all) the Most Beautiful Names belong to Allah, so call on Him by them, and leave the company of those who belie or deny (or utter impious speech against) His Names
The Names of Allah (swt) are those proper nouns/adjectives given in Quran by Allah (swt) Himself. Every one of these names refers to one or more attribute of Allah (swt). The meaning of al-husnaa الْحُسْنَى implies the utmost beauty, and that each name includes the quality of perfection
Each of these Name is derived from its verbal noun, such as All-Knowing, the Able, the All-Hearing, the All-seeing etc. The Name All-Knowing is derived from the attribute of “knowledge”.
Barely there is a Surat or even a single page of Quran that does not include a mention of Allah’s names and Attributes.
