Ибн Араби
As a Sufi, he was an authority on "Wahdt al Wujud", Sufism, and Muslim mysticism. The study of great Sufi, Ibn Arabi, and his masterpiece The Meccan Illuminations (Al-Futūḥāt al-Makkiyya) in 37 volumes was his specialisation. In his "Anwar Shamsia", Maulvi Ameer Baksh says that he was an ardent reader of Ibn Arabi book The Meccan Illuminations (Al-Futūḥāt al-Makkiyya), and was an authority on his teaching. He acknowledged Ibn Arabi superiority in philosophy and spiritual insight, but he never followed him if he found him deviating from Sunnah.
