Metaphysics is the branch of philosophy that examines the fundamental nature of reality, including the relationship between mind and matter, between substance and attribute, and between potentiality and actuality. The word "metaphysics" comes from two Greek words that, together, literally mean "after or behind or among [the study of] the natural". Metaphysics studies questions related to what it is for something to exist and what types of existence there are.
There are many Sunni scholars by this name. Ibn Al-Arabi Al-Maaliki (Abu Bakr) ( Died 543 Hijri) is a Sunni Shaikh who wrote Al-Awaasim Minal Qawassim العواصم من لقواصم. He was the person who claimed that Imam Husain (AS) by fighting against Yazeed, went against the teachings of his grandfather the Prophet (SAWA). He was clearly away from Ahlul Bayt (AS) and follower of Bani Umayyah who were ruling Andalusia where he was living.
Ibn Arabi (Mohyiddin) (Died 638 Hjri) , the Sufi Sunni scholar, is a different person who wrote Al Fotoohaat Al-Makkiyyah الفتوحات المكية . His books contain right and wrong things as he was not strictly following Ahlul Bayt (AS). He wrote some statements praising Ahlul Bayt (AS) but also wrote praising some enemies of Ahlul Bayt.
We have to be very careful when we read for such persons.
