He introduced criteria to differentiate between the Prophetic traditions that were meant to be part of Islamic law and the Prophetic actions/ sayings that were meant to be for the sake of specific purposes such as political leadership, court judgment, friendly advice, and conflict resolution. But Ibn Ashur’s most significant contribution in this book has been the development of new Maqasid by coining new, contemporary, terminology that were never formulated in traditional usul al-fiqh. For example, Ibn Ashur developed the theory of the ‘preservation of lineage’ into ‘the preservation of the family system’, the ‘protection of true belief’ into ‘freedom of beliefs’, etc. He also introduced the concepts of ‘orderliness’, ‘natural disposition’, ‘freedom’, ‘rights’, ‘civility’, and ‘equality’ as Maqasid in their own right, and upon which the whole Islamic law is based. This development opens great opportunities for Islamic law to address current and real challenges for Muslim societies and Muslim minorities.
Muhammad al-Tahir ibn Ashur was born in Tunis in 1879 and died in 1973. He left behind a wealth of long and detailed experience in public and administrative life as well a rich legacy of diverse and scholarly publications and articles absolutely unmatched in nineteenth and twentieth century Tunisia, many of which still await critical study and publication today.
