Is Allah described as "the Ancient (al-Qadim)," "the Thing (al-Shay)," "the Existent (al-Mawjud)," and "the Epoch (al-Huquw)"?

"Al-Qadim" (The Ancient/Pre-existent) is not one of Allah's Most Beautiful Names (Asma' al-Husna), but it is permissible to use it as an attribute when speaking about Him. It describes His dominion in the hadith "His Ancient Dominion." Similarly, "Al-Shay'" (The Thing) and "Al-Mawjud" (The Existent) are used to describe Allah, but they are not among His Most Beautiful Names. It is permissible to describe Allah as "Mawjud" (existent) as an attribute, but not as one of His Most Beautiful Names. And Allah's existence is known by necessity.
