All praise is due to Allah, and peace and blessings be upon our Prophet Muhammad.
Among words and names, there are those that denote perfection and those that do not. Those that do not denote perfection cannot be attributed to Allah, the Exalted, unless explicitly stated in the Islamic texts. If used, such terms must be restricted to the specific context in which they were revealed. On the other hand, if a word denotes perfection and is found in the Islamic texts, it can be attributed to Allah both in the specific context of its revelation and in other contexts. However, if a word denoting perfection is not found in the Islamic texts, the prevailing view among Ash'aris and the majority of Sunni scholars is that it is impermissible to attribute such a name to Allah unless it has been used by Him in the Quran or there is a consensus among the Muslim community on its usage."
This is what Ahlu Sunnah Wal Jama`ah mean when they say that the names of Allah, the Exalted, are 'tawqīfī.' I.e. it is not permissible to attribute any name to Allah unless there is a clear authorization from the Islamic texts for doing so.
In addition, the source of this authorization is the Quran, the Sunnah, and the consensus of the Muslim community. It is not a condition for the permissibility of attributing a name to Allah that the evidence be absolutely certain; rather, it is sufficient that the evidence be sound or authentic. Imam al-Zarkashi, may Allah have mercy upon him, stated: 'It is not a condition for the permissibility of attributing a name that the evidence be absolutely certain; rather, it is sufficient that the evidence be sound.'
For this reason, the scholars have established the principle that it is impermissible to attribute to Allah names that are synonymous with His established names. For example, it is permissible to say 'Ya Jawad (One of the established Names of Allah),' but it is not permissible to say 'Ya Sakhi (Not one of the established Names of Allah)' or 'O Wise,' 'O Physician,' or 'O Jurist,' even though He is indeed the Knower of all diseases, their causes, and their cures, as He is their creator and originator. Similarly, He is the Knower of all Sharia rulings and their reasons, as He is their source and revealer.
Therefore, it is impermissible to attribute Syriac names to Allah, the Exalted, if they are not mentioned in the Islamic texts. It is also not permissible to mention Allah or make supplication using such names. This is out of fear that these names may contain meanings that are not befitting of Allah, similar to the prohibition of making Ruqyah (Healing method based on the Quran and Hadith in the treatment of diseases) in non-Arabic languages. Imam al-Iraqi, may Allah have mercy upon him, stated: 'All Ruqhyas are permissible if they are in the Quran or contain the remembrance of Allah. However, they are prohibited if they are in non-Arabic languages or if their meaning is unknown, as there is a possibility that they may contain disbelief .' And Allah the Almighty knows best."
