The verse does not imply a deity above Allah. The strongest reading in the Islamic tradition is that Allah is revealing the words of the angels, especially Jibril, explaining that they only descend by Allah's command.
The force of the critic's reading
The objection is not silly. In Surah Maryam, Allah speaks, then the text says:
"And we do not descend except by the command of your Lord. To Him belongs what is before us and what is behind us and what is between that. And your Lord is never forgetful."
Quran 19:64
If someone assumes that every first-person plural in the passage must be Allah speaking directly about Himself, then "we descend" and "by the command of your Lord" sound strange. Allah does not need permission from a higher Lord. So the objection depends on one key claim: that there is no legitimate shift of speaker here.
Why the speaker is understood as the angels
The words themselves point away from Allah as the immediate "we." The verb "descend" fits angels who come down with revelation. The phrase "by the command of your Lord" fits servants under command. And "what is before us and what is behind us" sounds like limited creatures describing their assigned ranks and movements, not the Lord of all existence.
This is exactly how the verse was understood from the earliest period. A report in al-Bukhari connects the verse to the Prophet Muhammad (PBUH) asking Jibril why he did not visit more often:
The Prophet (PBUH) said to Jibril, "What prevents you from visiting us more often than you visit us?" Then the verse was revealed: "And we do not descend except by the command of your Lord..."
Sahih al-Bukhari
So this is not a late rescue attempt. It is the standard explanation found in the earliest transmitted tafsir: these are the words of Jibril or the angels, revealed by Allah in the Quran.
Allah's speech can include quoted speech
Muslims believe the Quran is the speech of Allah. That does not mean every first-person pronoun inside the recited text refers to Allah as the one being quoted. The Quran contains the words of believers, prophets, angels, disbelievers, and even Satan, all recited as Quran because Allah revealed them.
Sometimes the Quran introduces speech with "he said" or "they said." Sometimes the speaker is known by context. Classical Arabic often allows this, especially in elevated, compact discourse. The absence of the word "angels" is not proof that the speaker cannot be angels; the internal wording and the Prophetic explanation identify them.
The surrounding passage also supports this. Verse 63 speaks of Paradise inherited by the God-fearing, then verse 64 answers why revelation or angelic visitation comes only at appointed times, then verse 65 returns to the majesty of Allah:
"Lord of the heavens and the earth and whatever is between them, so worship Him and be constant in His worship. Do you know of any equal to Him?"
Quran 19:65
That is the opposite of suggesting another god above Allah.
What this does and does not establish
The verse does show that Quranic speech may move between narration, quotation, and direct address without always using a formula like "they said." That is normal in Arabic and recognized by the commentators.
It does not establish that Allah has a Lord above Him. The words "we descend" are unsuitable for Allah in this context, suitable for angels, and explained by an authentic report about Jibril. The objection only works by forcing one speaker onto a passage whose language and early explanation indicate a shift.
So the passage is not incoherent monotheism. It is a concise Quranic quotation of angels who descend only when Allah commands them.
