Ibn Isḥāq (d.151/768) and Wāqidī (d. 207/823) are the two most important scholars in the siyar history. Both pioneered the Islamic Historians who came after them. This leadership has seen in the texts of the narrations as seen in the transfer methods. Much of Ibn Ishāq’s work has been transferred to the present day by Ibn Hisām. This work begins with the generation of the Prophet Muhammad extending to the Prophet Ādam and continues with the life of the Prophet Muhammad. The work of Wāqidī covers the military expeditions and gazvahs of the Prophet Muhammad. Ibn Isḥāq and Wāqidī narrated in his own books the famous siyar and hadith scholar Zuhrī. However, Wāqidī did not receive any narrations directly from Ibn Isḥāq, one of the famous students of Zuhrī. His attitude attracted the attention some orientalists, such as Horovitz and Wellhausen, and saw this suspicious. They stated that in order to support these doubts, some sections of Ibn Isḥāq’s Sīra and Wāqidī’s Kitābu’l-Maghāzī were very similar. Based on this claim, it was tried to determine whether or not Wāqidī used in his narrations in a secret manner. Although these two authors live in the same period, we can’t reach any clear information about whether they are directly in contact with each other. Although sources say that Ibn Isḥāq is the teacher of Wāqidī, we do not see a first-ever explanation from both of them. For this reason, it was tried to find out whether Wāqidī made plagiarism based on the narrations in Ibn Isḥāq's Sīra and Wāqidī's Kitābu’l-Maghāzī. In our study, we reached the conclusion that Wāqidī did not transmit a secret way from Ibn Isḥāq and that he narrated his narrations in his own style and isnād method.
