What is the ruling on swearing oaths and making supplication by the Face of Allah the Exalted?

Question:
May Allah reward you. Honorable Shaykh, he says: What is the ruling on swearing oaths and making supplication by the Face of Allah the Exalted?

Answer:
There is nothing wrong with swearing by the Face of Allah. Swearing by Allah’s intrinsic attributes or His conceptual attributes, such as the speech of Allah and the life of Allah (Mighty and Majestic), is permissible. Swearing by Allah or by His names and attributes is permissible, because the names and attributes of Allah are attached to His essence (Glorified and Exalted is He). As for...
Supplicating to Him by His names and attributes is good; it is prescribed to supplicate to Allah by His names and attributes, . So you say, “O Merciful, have mercy on me; O Generous, be generous to me; O Forgiver, forgive me; O Allah, forgive me, for You are the One who accepts repentance and is Merciful.” One supplicates to Allah by His names and attributes; this is prescribed. It is seeking nearness to Allah (tawassul) through His names and attributes, and it is a place where the supplication is likely to be answered, so supplicate to Him by them.
