The Jam' al-Jawami' of Imam Taju Din Ibn Subki stands out as the foremost relied work in issues pertaining to Usul al-Fiqh. Imam as-Suyuti has compiled versification or poem form (1480 Verses) of the Jam' al-Jawami' which in his words have not been done before and also similarly the same is emphasised by the commentator that since Suyuti, there has not been versification of this fundamental work. It is a well presented work with various notes and explanatory emphasis on what can be said one of the hardest sciences in Islamic traditions. Commentator is Muhammad ibn Ali ibn Adam al-Itiyubi.
