Ibn Arabi, known as Muhyiddin (638 AH), was unanimously considered a heretic and infidel. Regarding his heretical beliefs based on philosophy and the Sufism of Unity of Existence, Hafiz Dhahabi رحمه الله (748 AH) writes:
من أردإ تواليفه كتاب الفصوص، فإن كان لا كفر فيه، فما في الدين كفر، نسأل الله العفو والنجاة.
"The worst of his books is Al-Fusus. If there is no disbelief in it, then there is no disbelief anywhere in the world. We seek refuge and salvation from Allah, the Exalted."
Allama Taj al-Din Subki رحمه الله (771 AH) writes:
من كان من هؤلاء الصوفية المتأخرين كابن عربي وغيره، فهم ضلال جهال، خارجون عن طريقة الإسلام، فضلا عن العلماء.
"Among the later Sufis, those like Ibn Arabi are misguided, ignorant, and have deviated from the path of Islam, let alone that they should be counted as scholars."
Hafiz Ibn Hajar رحمه الله (852 AH) writes about the life of Ibn al-Farid:
قد كنت سألت شيخنا الإمام سراج الدين البلقيني عن ابن عربي، فبادر الجواب بأنه كافر.
"I asked my Sheikh Siraj al-Din Umar ibn Ruslan al-Balqini (807 AH) about Ibn Arabi, and he immediately replied: He is an infidel."
Hafiz Ibn Kathir رحمه الله (774 AH) writes about Ibn Arabi's book Fusus al-Hikam:
فيه أشياء كثيرة ظاهرها كفر صريح.
"There are many things in it whose apparent meaning is clear disbelief."
Allama Baqai رحمه الله (885 AH) writes:
وبعد، فإني لما رأيت الناس مضطربين في ابن عربي المنسوب إلى التصوف الموسوم عند أهل الحق بالوحدة، ولم أر من شفى القلب في ترجمته، وكان كفره في كتابه الفصوص أظهر منه في غيره، أجبت أن أذكر منه ما كان ظاهرا، حتى يعلم حاله، فيهجر مقاله، ويعتقد انحلاله، وكفره وضلاله، وأنه إلى الهاوية مآبه ومآله.
"After the Salat upon Muhammad, when I saw people in confusion regarding this Ibn Arabi, who is attributed to Sufism and was considered a proponent of Unity of Existence (a polytheistic belief), I did not see anyone write about his (complete) circumstances to reassure the heart, and his disbelief was more evident in his book Al-Fusus than in other books, so I preferred to mention his apparent situation, so that his (religious) state may be known, and his sayings may be disregarded, and the belief that he is outside of Islam, an infidel and misguided, and that his abode is in Hell may be established."
About fifty scholars and judges have declared him a heretic, an atheist, and an infidel. Mulla Ali al-Qari Hanafi wrote a book named الرَّدُّ عَلَى الْقَائِلِينَ بِوَحْدَةِ الوُجُودِ on his disbelief.
Hafiz Suyuti رحمه الله (911 AH) writes:
يحرم تحريما غليظا أن يفسر القرآن بما لا يقتضيه جوهر اللفظ، كما فعل ابن عربي المبتدع، الذي ينسب إليه كتاب الفصوص الذي هو كفر كله.
"It is strictly forbidden to interpret the words of the Holy Quran in a manner that is not required by them, as Ibn Arabi the innovator has done. The book attributed to him is called Al-Fusus, which is a manifestation of disbelief."
