How Quran and Hadith can be used in working out the Islamic Law — Islamic Education
The Holy Quran constitutes the foundation of Islamic Law and is, therefore, the primary and most reliable source. All other sources must be in conformity with the Quranic injunctions. It is the final word of Allah Almighty revealed to the last messenger, Hazrat Muhammad The Holy Prophet ﷺ then conveyed the Divine message to the people for guidance to the Right Path.
The Quran in this regard says:
… Judge between them by what Allah has revealed, and follow not their vain desires (Maida; 5:49)
….if any do fail to judge by what Allah has revealed, they are unbelievers. (Maida; 5:44)
The Holy Prophet ﷺ said,
Whomsoever desired guidance from any other except the Quran, shall go astray.
Commandments derived from the Holy Quran are called ‘Nas’ (Plural Nussus). The compulsory acts of worship, such as Salat, Zakat, Saum, Hajj are all direct Nussus of the Holy Quran. Furthermore, the laws of inheritance, marriage, and divorce are all found in detail in the Holy Quran. These instructions are invariable and must be followed by all Muslims for all times to come. Refusal to obey any Nas of the Quran leads to kufr, disbelief.
