Ahmad bin Muhammad bin Hanbal Abu `Abd Allah al-Shaybani (Arabic: احمد بن محمد بن حنبل ابو عبد الله الشيباني‎) was an important Muslim scholar and theologian. He is considered the founder of the Hanbali school of fiqh (Islamic jurisprudence). Imam Ahmad is one of the most celebrated Sunni theologians, often referred to as "Sheikh ul-Islam" or the "Imam of Ahl al-Sunnah," honorifics given to the most esteemed doctrinal authorities in the Sunni tradition. Imam Ahmad personified the theological views of the early orthodox scholars, including the founders of the other extant schools of Sunni fiqh, Imam Abu Hanifa, Imam Malik ibn Anas, and Imam ash-Shafi`i.

Ahmad ibn Hanbal's family was originally from Basra, Iraq, and belonged to the Arab Banu Shayban tribe. His father was an officer in the Abbasid army in Khorasan and later settled with his family in Baghdad, where Ahmad was born in 780 CE.

Ibn Hanbal had two wives and several children, including an older son, who later became a judge in Isfahan.

Maulana Tariq Jameel (Urdu: مولانا طارق جمیل) (born 1953) is an Islamic scholar from Pakistan. His native town is Tulambah near Mian Channu. His father was an agriculturist who belonged to the Muslim Rajputs community.^{[citation needed]}

Tariq Jameel was born and raised in Mian Channu. In his childhood he lived a relatively modest life but religion was not a major part of his life and his family in particular. It wasn't until he pursued his M.B.B.S. in Lahore that his focus shifted towards Islam. After completing his Higher Secondary School education (a.k.a. F.Sc in some regions of Pakistan) in pre-medical (equivalent to A 'levels') from Government College, Lahore, he took admission in King Edward Medical College in Lahore. He intended to do his M.B.B.S., but he soon switched to Islamic education. He then went on to receive Islamic education from Jamia Arabia, Raiwind (near Lahore), Pakistan where he studied Quran, Hadith, Sharia, Tasawwuf, logic and Fiqh.^{[citation needed]}

His proclivity towards Islam grew during hostel life in Lahore and can mainly be attributed to the group members of Tablighi Jamaat who he became friends with during his college life.^{[citation needed]}
