Praise be to Allah, and peace and blessings be upon the Messenger of Allah.
“Ar-Rashid” is not among the established Names of Allah تعالى according to the view stated in this fatwa, because it has not been established in the Qur’an or in the authentic Sunnah that Allah تعالى was given this name. The Names of Allah تعالى are based upon revelation, so it is not permissible to affirm a name for Him without evidence from the Qur’an or the authentic Sunnah. Islam-QA
The basic principle regarding the Beautiful Names of Allah is that a Muslim restricts them to what has been established by textual evidence. Therefore, Allah تعالى should not be given a name that does not occur in the Qur’an or authentic Sunnah, even if the name carries a sound meaning or indicates an attribute of perfection.
This is because the Names of Allah تعالى are not a matter for unrestricted personal reasoning. Rather, they are taken from what Allah has named Himself or what His Messenger صلى الله عليه وسلم named Him. Islam-QA
Yes. “Ar-Rashid” appears among the well-known list of names attributed to the hadith of Abu Hurayrah in At-Tirmidhi. However, the enumeration of the Names in this form in that narration is not considered authentic by a number of leading hadith scholars, and therefore this enumeration is not sufficient to establish the Name. Awqaf Online
This is why scholars have differed concerning the enumeration of the Beautiful Names of Allah. Some affirmed certain Names through inductive examination or according to particular criteria, while others required that the Name be established by an explicit authentic text.
The meaning of guidance, right direction, correctness, and wisdom may be established for Allah تعالى in terms of meaning. However, this does not necessarily mean that the word “Ar-Rashid” is an established Name among His Beautiful Names.
The principle is: Not everything whose meaning is correct may necessarily be made into a Name of Allah تعالى, because the matter of Divine Names is more restricted than the matter of describing or informing about Allah. A valid name requires recognized textual evidence. Islam-QA
According to the view adopted in this fatwa, it is not correct to count “Ar-Rashid” among the Beautiful Names of Allah, because it has not been established in the Qur’an or the authentic Sunnah. What appears in some lists of the Names is not sufficient to establish it, because the enumeration of the Names in the aforementioned narration has not been authenticated by a number of hadith scholars.
And Allah knows best.
