1. The sources of Islamic law are divided into two categories - definitive sources that are universally accepted, and disputed sources. The definitive sources include the Quran, Sunnah, Ijma, and Qiyas. 2. Ijtihad refers to the effort of a qualified jurist to derive a legal ruling through independent reasoning and interpretation of the primary sources where the ruling is not explicit. There are different methodologies a jurist can use in conducting ijtihad. 3. When interpreting Islamic legal texts, jurists may examine the plain meaning of words as well as implied meanings and connotations to derive legal rulings in a way that accomplishes the objectives and spirit of the Shariah.
