کان الفقيه عبد الله بن مسرور القيرواني المعروف بابن الحَجَّامِ (ت346ه/958م)، من شيوخ المالکية الثقات الذين نقل عنهم العلم. وقد تتلمذ عليه کثير من طلاب العلم القيروانيين والأندلسيين، فسمعوا منه مصنفاته العلمية، وکتب الفقه المالکي، ومصنفات ابن سنجر الجُرجاني نزيل مصر، وهى مفقودة، برواية شيخه عيسى بن مسکين، ثم حدّثوا بها تلاميذهم بنواحيهم فذاعت هناک. ومع ذلک کان ابن الحَجَّامِ من العلماء الذين لم ينصفهم التاريخ، فلم ينل قدره من الاهتمام الذي يتناسب وقيمته العلمية. وتستهدف الدراسة إبراز ملامح دوره في الحياة العلمية بإفريقية والأندلس، وأثره في تشکيل ثقافة تلاميذه منذ أواخر القرن الثالث حتى قرابة منتصف القرن الرابع الهجريين، مما أهّل بعضهم ليصبحوا من أبرز شيوخ الفقه والحديث ببلادهم. وتستهدف الدراسة أيضًا إبراز موقف ابن الحَجَّامِ المعارض للمد الشيعي الفاطمي بإفريقية وتأثر تلاميذه القيروانيين بذلک، وميله نحو الزهد واقتداء تلاميذه القيروانيين والأندلسيين به.
  The jurist Abdullah ibn Masror al-Kairouani, known as Ibn al-Hajjam (T346Ah/958 AD), was one of the reliable Maliki sheikhs who were transferred from the flag, and many students of the Kairouan and Andalusian sciences studied it. They heard from him his scientific works, the books of Maliki jurisprudence, and the works of Ibn Sinjar al-Gurgani, the guest of Egypt, which is missing, in the novel of his sheikh Isa ibn Miskine, and then they talked to their disciples in their areas, and they went there.
   Nevertheless, Ibn al-Hajjam was one of the scholars who had not been distinguished by history, and he did not receive the attention commensurate with its scientific value. The study aims to highlight the features of his role in the scientific life of Africa and Andalusia, and its impact on the formation of the culture of his disciples from the late 3rd century until the middle of the fourth century Hijri, which qualified some of them to become the most prominent elders of jurisprudence and hadith in their country. The study also aims to highlight ibn al-Hajjam's position opposed to the Fatimid Shiite tide in Africa, influenced by his Kairouan disciples, and his propensity for asceticism and the example of his Kairouan and Andalusian disciples
