Peringkat pertama dalam perkembangan Fiqh meliputi zaman kerasulan Nabi Muhammad ibn ‘Abdillaah ﷺ (609-632 M), ketika satu-satunya sumber hukum Islam ialah wahyu ilahi, sama ada dalam bentuk al-Qur’aan atau al-Sunnah [perkataan dan perbuatan Nabi ﷺ]. Al-Qur’aan menjadi cetak biru bagi kehidupan harian baginda ﷺ, manakala al-Sunnah berfungsi sebagai penjelasan terperinci terhadap prinsip-prinsip umum yang digariskan dalam al-Qur’aan, serta contoh praktikal bagi penerapannya.

The first stage in the development of Fiqh covers the era of the Prophet Muhammad ibn ‘Abdillaah’s apostleship (609-632 CE) during which the only source of Islamic law was divine revelation in the form of either the Qur’aan or the Sunnah [the saying and actions of the Prophet (SW.)]. The Qur’aan represented the blueprint in his day-to-day life (i.e. the Sunnah) acted as a detailed explanation of the general principles outlined in the Qur’aan as well as a practical demonstration of their application.
