Abstract

The generation of companions who played a key part in writing the revelation continued this responsibility in maintaining the Sunnah and translating it to some extent. Since the Sunnah is the secondary source of religion, this activity of theirs is of great importance. In this regard, the fact that some of the companions documented the Sunnah when the Prophet was still alive or after his death yielded favorable outcomes in terms of Sirah science, which attempts to properly transmit his life from birth to death. In the research, the location of the written material, which was penned by the companions and identified as “codex” or “kitāb”, in the formation process of the science of Sirah will be tried to be revealed. Because the codexes, which include the majority of the narrations relating to the ghazwa and seriyyas, are among the most important sources used by Tabi'un era Sirah scholars. In the research, the principal sources of Sirah and Islamic History were taken as a basis, recent literature was scanned and academic works on the subject were benefited from. It is seen that the offspring of the companions developed the codex, who inherited from their dads or grandfathers, with the narrations they received from third parties. This is why the research briefly mentions these important contributions they made.
