Answer
The primary sources of Shari?ah are the Qur’aan and the Sunnah (Ahaadith of Nabi (Sallallaahu Alayhi Wasallam).
Apart from these, Qiyaas (analogy) and Ijmaa (consensus of opinion of the jurists) constitute secondary sources. All of these play an extremely active role in Islamic law. The Fuqahaa (Jurists) have thoroughly analysed these sources and have extracted a set of principles which are actively employed in legislation. These principles are known as al-Qawaaidul Fiqhiyyah (legal maxims) and have been unanimously accepted by the Fuqahaa of Islam.
