Describing Allah the Exalted with the attribute of antiquity

Question:
Is it permissible to describe Allah the Exalted with the attribute of antiquity; for example, if someone says: "O Ancient One, have mercy on me!" or something similar? And is "The One" (al-Fard) among the names of Allah the Exalted?

Answer:
"The Ancient One" (al-Qadim) is not among the names of Allah the Exalted; rather, "The First" (al-Awwal) is among His names. Likewise, "The One" (al-Fard) is not among His names; rather, "The One, the Unique" (al-Wahid al-Ahad) is among His names. Therefore, it is not permissible to say: "O Ancient One!" or: "O One (al-Fard)! Have mercy on me!" Instead, one should say: "O He who is the First and the Last, the Manifest and the Hidden! O One, the Unique, the One (al-Fard), the Self-Sufficient! Have mercy on me and guide me... and so on. This is because the names of Allah the Exalted are based on divine revelation (taqwiyyah), and it is not permissible for anyone to affirm any of them without evidence.
