The responsible ?akim passes judgement on the “mugab of her iqrar”. What impact does this judgement have? Is it valid? What does “mugab of the iqrar” mean? And what in fact does “mugab” mean? Why does the ?akim not pass judgment on the legal validity of the endowment? And what role does the notarization play in this judgement? Taqi ad-Din Abu l-?asan ?Al? as-Subki, Imam and Supreme Cadi, addresses this controversial judgement as well as other issues in this manuscript “al-Qaul al-mu?ab fi l-qa?a?bi l-mugab”.
