Are the hadiths that say, "Swear by my stature, for my stature with Allah is great," authentic? And is the saying "Allah the Almighty has spoken the truth" an innovation? And what is the ruling on saying "O Key, enlighten me" to the Prophet?

The hadith with the wording "I seek intercession with You by the prestige of Muhammad" has not been found. The similar wording "Seek intercession by my prestige" is a fabricated hadith. The invalidity of the first wording is indicated by the prohibition of swearing by other than Allah, as the Prophet, peace and blessings be upon him, said: "Whoever swears by other than Allah has committed shirk."
