What is the authenticity of this supplication and these statements attributed to al-Ayyashi regarding the ذكر (remembrance) of the Divine Names "al-Kafi (The Sufficient), al-Ghani (The Self-Sufficient), al-Fattah (The Opener), al-Razzaq (The Provider)" 100 times after Fajr prayer, or 100,000 times with the intention of fulfilling needs, and that it is a secret not to be disclosed to the ignorant, given the time constraints and the attempt to gather means of travel when there were no mounts; so, is this supplication and that secret authentic?

Supplicating with the Beautiful Names of Allah is permissible, as Allah says: "And to Allah belong the Beautiful Names, so invoke Him by them." However, supplicating with a single Name from them, such as "Allah" or "Al-Kafi" (The All-Sufficient), is impermissible. A single Name is not a complete utterance or a beneficial sentence, and no faith or disbelief is consequent upon it. Neither the Salaf nor the Messenger of Allah, peace be upon him, did this, and it is a means to innovations and misguided practices. As for the supplication after Fajr prayer in the manner and with the numbers mentioned, its attribution to the Prophet, peace be upon him, is incorrect. It is advisable to engage in the authentic, transmitted supplications. There is no harm in supplication and remembrance with specific numbers or at special times, provided that one does not believe in a particular virtue for these numbers if it is not mentioned in the Sunnah, and that it is not considered a Sunnah from the Prophet, peace be upon him.
