Ibn al-Mibrad
Jamāl al-Dīn Yūsuf ibn ʻAbd al-Hādī al-Salihi, commonly known as Ibn al-Mibrād was a Syrian Muslim scholar of the Hanbali school of thought. His magnum opus is considered by later Hanbalis to be the Ghāyat al-sūl ilā ʿilm al-uṣūl, an introductory treatise into principles of Islamic jurisprudence within the context of the Hanbali methodology. He was a direct descendant of the second Rashidun caliph, Umar ibn al-Khattab.
