It says in Al-Din al-Qayyim, written in Arabic by Mawlana Habib Ahmad al-Kiranawi under the supervision of Hakim al-Ummah Mawlana Ashraf ‘Ali al-Thanawi as part of the general introduction to the 20-volume compendium of hadith-proofs for the Hanafi madhhab, I’la al-Sunan,

“This question and this answer are baseless because no one claimed that the ‘ulama are to be obeyed independently, rather independent obedience is specific to Allah (Exalted is He), and the Messenger is only obeyed because He is an informant of the rules of Allah, and the ‘ulama are obeyed because they are informants of the rules of Allah and His Messenger. Hence, the claim that the obedience of the Messenger is independent is false.” (Al-Din al-Qayyim, p.34)

Imam Ghazali writes in Al-Mustasfa min ‘Ilm al-Usul, p.8:

وفي البحث عن الحاكم يتبين أن لا حكم إلا لله وأنه لا حكم للرسول ولا للسيد على العبد ولا لمخلوق على مخلوق بل كل ذلك حكم الله تعالى ووضعه لا حكم لغيره

“In discussing the Ruler, [we] demonstrate that there is no rule except for Allah; and [in fact], the Messenger has no rule; nor a master over his subject; nor any creature over other. Certainly, all Rule belongs to Allah and His imposition. Non other than Him has rule.”

More quotes by the scholars of Islam on this topic as mentioned by Shaykh Sarfaraz Khan Safdar.

[1] Shaykh al-Islam ‘Allamah Badr al-Din ‘Ayni (d. 855H) writes, “Indeed, legalization (tahlil) and prohibition (tahrim) is from Allah alone, humans have no say in this matter.” (‘Umdat al-Qari, 12:745)
ان التحليل والتحريم من عند اللّه لا مدخل لبشر

[2] Imam Shah ‘Abd al-’Aziz Dahlawi (d. 1239H) writes, “Correct madhab is that the matter of legislation is not entrusted to prophet; since it is a post of messenger and emissary and not deputy of Allah and not an associate in His affairs. Whatever is regarded halal and haram (lawful and unlawful) by Allah, it is only preached by a prophet, he has no power on his own.” (Tuhfah Ithna ‘Ashariyyah, p.335)
مذهب صحيح آنست كه امر تشريع مفوض به ۑيغمبر نمى باشد زيرا كه منصب ۑيغمبرى منصب رسالت وايلچى گريمت نه نيابت خدا نه شركت دركارخانه خدائى آنچه خداۓ تعالى حلال وحرام فرمايد آں را رسول تبليغ مى كند وبس ازطرف خود اختيارے ندارد

He writes at another place, “It is obvious that imam and even a prophet is not a lawmaker (Shar’i), lawmaker is Allah Most High alone.” (Tuhfah Ithna ‘Ashariyyah, p.361)
بديهى است كه امام بلكه نبى نيز شارع نيست شارع حق تعالى است

[3] Shaykh ‘Abd al-Wahhab Sha‘rani (d. 772H) quotes from Shaykh Muhyi al-Din ibn ‘Arabi (d. 638H) as follows, “Know that lawmaker (Shar’i) is only Allah … the Prophet (Allah bless him and give him peace) only delivers the message of Allah which He likes, the Prophet never speaks out of his own desire [in the matters of Religion] and does not forget any thing for which he was ordered to preach, it is but revelation revealed [to him].” (Al-Yawaqit wa ‘l-Jawahir, 2:42)
ونحن نعلم ان الشارع هواللّه تعالى٠٠٠ـ فانه صلى اللّه عليه وسلم مبلغ عن اللّه احكامه فيما اراده اللّه تعالى لا ينطق قط عن هوى نفسه ولا ينسى شيئا مما امره بتبليغه ان هو الا وحى يوحى

[4] Shaykh ‘Abd al-Haq Muhaddith Dahlawi (d. 1052H) writes, “The prohibition (tahrim) was attributed to the Prophet Ibrahim (may the peace of Allah be upon him) in a way that he preached it and spread the divine command; since it is only Allah who makes law and gives commandments and His command is eternal (qadim). The prophets are emissaries to convey the message.” (Ashi’ath al-Lam‘at, 2:178)
اسناد تحريم بابراهيم عليه السلام از جهت آں باشد كه وے رسانيد واعلام كرد حكم الهى زيرا كه حاكم بشرائع واحكام خداتعالى است وحكم وے قديم است انبيأ عليهم السلام رساننده آں احكام اند

[5] ‘Allamah Sayf al-Din al-Amidi al-Shafi’i (d. 631H) writes, “Know that there is no absolute master but Allah and there is no command (hukm) but which is ordained by Him. From this it can be derived that the mind neither knows good and bad nor obligates thankfulness to benefactor, and there is no command before revelation of the law (Shar’a).” (Al-Ihkam fi-Usul al-Ahkam, p.113)
علم انه لا حاكم سوى اللّه تعالى ولا حكم الا ما حكم به ويتفرع عليه ان العقل لا يحسن ولا يقبح ولا يوجب شكر المنعم وانه لا حكم قبل ورود الشرع

[6] ‘Allamah Bahr al-’Ulum (d. 1225H) writes in Sharh Musallam al-Thubut, “In this matter that judgment (hukm) is from Allah alone, there is a consensus (Ijma’) of Ummah.”
