يحيى بن سعيد الأموي المتوفى سنة 194هـ، من الأعلام الثقات، درس على عدد من الشيوخ، وله تلاميذ عديدين، هو أحد الأخباريين الذين کتبوا في السيرة النبوية وتاريخ صدر الإسلام، وله کتاب في المغازي. وتناول هذا البحث رواياته التي بلغت مئة وثمانية وعشرين رواية في تاريخ ما قبل مولد النبي r، وفي العهد المکي، وبيعتي العقبة، وروايته في العهد المدني، ورواياته عن زوجات الرسول الکريم r وبعض مغازيه وسراياه، سأقوم بجمعها ودراستها، والحکم عليها من حيث الصحة وعدمها، وتحديد مصادره التي نقل عنها. Yahya bin Saeed al-Umayyad, who died in 194 AH, was a trustworthy scholar. He studied with a number of sheikhs, and he has many students. He is one of the Akhbaris who wrote on the Prophet's biography and the history of early Islam, and he has a book on Maghazi. This research dealt with his narrations, which amounted to one hundred and twenty-eight narrations in the history before the birth of the Prophet, may God bless him and grant him peace, and in the Meccan era, and the pledges of allegiance to Aqaba, and his narrations in the civil covenant, and his narrations about the wives of the Noble Messenger, may God's prayers and peace be upon him, and some of his battles and brigades. I will collect and study them, judge them in terms of validity and lack thereof, and determine the sources that were quoted from them.
