Sheikh Abdel-Halim Mahmoud (Arabic: الإمام الأكبر عبدالحليم محمود) (12 May 1910 – 17 October 1978; 2 Jumaada al-awal 1328 A.H. - 14 The al-Qi`dah 1398 A.H.) served as Grand Imam of Al Azhar from 1973 until his death in 1978. He was known for his modernizing approach to teaching at Al Azhar, preaching moderation and embracing modern science as a religious duty.
For Mahmoud, "any reform -- whether on the personal level or on the level of society -- begins with science, be that science religious or material..... Whether we begin the path of reform from the vantage point of theoretical science or from that of material or empirical science, our endeavours must be imbued with a purpose. This purpose is an Islamic obligation, as science must be the basis for the path towards God. Indeed, knowledge is a form of worship and a form of jihad."
During his tenure as Grand Imam, Al Azhar witnessed unprecedented reform and revival, including the introduction of new faculties, teaching methods and management style.
Abdel-Halim Mahmoud is also remembered for reviving Sufism through his prolific writings and lectures on the matter.
"Abd al-Halim Mahmud (1910-1978) is remembered as the former rector of al-Azhar who wrote a great deal on Sufism. He is referred to by his honorific title, 'al-Ghazali, in 14th Century A.H.'2, a title he was given because of his unique ability to integrate the exoteric and esoteric dimensions of Islam (which are often considered contradictory at first glance). He became influential in 1960-1970s, the Sadat period in which Islamic revivalism began its rise to prominence in Egypt."
"Abd al-Halim presents tasawwuf as a scientific method that would enable people to comprehend the ultimate reality. The essence of tasawwuf is defined as knowledge (ma`rifa) of the metaphysical domain. Metaphysics is the science of explaining the hidden aspects of God and clarifying his prophecies. He emphasised its distinction of 'mysticism'-he proposed that tasawwuf is not a mere superstitious method, but a field of science (Mahmud Al-Munqidh: 224-233). `Abd al-Halim cites `Abbas Mahmud al-`Aqqad (d. 1964) in saying that ma`rifa is an intellectual realm which neither physical science, cognition (fikr), nor various types of mental perception (basira etc.) have access to. Tasawwuf is the only science that can enter this realm, because although other sciences are bound to human capacity, tasawwuf is not (cited from ibid. 352-353)."
"Abd al-Halim's Sufism consists of three elements-`ilm, jihad, and `ubudiya. First was `ilm, the knowledge of Islamic Law. He emphasizes the significance of living according to shari`a, and stipulates that Islamic Law is to be understood and practiced accordingly. Moreover, he cites Abu Hamid al-Ghazali's work, which declares that God will bless those who acted according to their knowledge of Law-no matter how ignorant they might be-but would punish those who ignored the law irrespective of their knowledge4. Second is jihad, the effort to situate oneself within social reality and to solve the problems one faces. `Abd al-Halim's ideal image of Sufi is not exemplified through the concept of 'mystic' (those who live in seclusion, practicing asceticism). He states rather that Sufi must be committed to solving the problems of the time, and gives the example of `Abd al-Qadir al-Jazai'rli (d.1883), who fought for the defence of Algeria against France (ibid. 15-16). Third is `ubudiya, servitude to God: being correct and devoted. When `ubudiya is attained, ma`rifa is granted, and God showers the believer with Mercy (ibid. 12)".
