Tahap ini mewakili masa Khulafaur Rasyidin dan para Sahabat besar Nabi Muhammad ﷺ. Tahap ini berlangsung dari kekhalifahan Abu Bakr (632-634 M) hingga negara Islam yang berkembang pesat selama dua puluh tahun pertama tahap ini, mencakup Syria, Yordania, Mesir, Irak, dan Persia. Dengan demikian, kaum Muslimin tiba-tiba bersentuhan dengan sistem, budaya, dan pola perilaku yang sama sekali baru, yang belum ada ketentuan khususnya dalam hukum Syari'ah. Untuk menghadapi banyaknya persoalan baru tersebut, Khulafaur Rasyidin sangat mengandalkan keputusan berdasarkan konsensus (Ijmaa') serta Ijtihaad, yang telah mereka latih oleh Nabi ﷺ ketika mereka bersama beliau setelah hijrah beliau ke Madinah. Dalam perjalanan penggunaan Ijmaa' dan Ijtihaad yang luas, para khalifah ini menetapkan prosedur-prosedur yang kemudian menjadi dasar bagi legislasi dalam Islam, yaitu Fiqh.

This stage represents the era of the Righteous Caliphs94 and the major Sahaabah (companions of the Prophet (s.w.). It extends from the caliphate of Abu Bakr (632-634CE) to the Islamic state were rapidly expanded during the first twenty years of this stage to include Syria, Jordan, Egypt, Iraq, and Persia. Thus, Muslims were suddenly brought into contact with totally new systems, cultures, and patterns of behavior for which specific provision was not to be found in the laws of Sharee’ah. To deal with the numerous new problems, the Righteous Caliphs relied heavily on decisions by consensus (Ijmaa’) as well as Ijtihaad, in which they had been trained by the Prophet (s.w.) while they were with him after his migration to Madeenah. In the course of their extensive use of Ijmaa’ and Ijtihaad, these caliphs established procedures which later became the basis for legislation in Islaam, that is Fiqh.
