The first and foremost thing that was given priority in the Islamic history was the Sīrah of the Prophet  and the subsequent military campaigns (maghazi) that followed. For this, reliance was placed on ahadīth narrated by the Sahabah, Tabi'een and those who came after them concerning the life of the Prophet ; from his birth, his early life, and his Call to Islam to the Jihad and military expeditions against the Mushrikin and his conquests. In short, reports concerning the Prophet  from his birth till his death.

The history of the Prophet's life  was a part of the reported ahadīth. Such ahadīth used to be miscellaneous in the days when the Muhaddith would compile all the reports that reached him and learn them without any order or arrangement. When ahadīth came to be arranged according to chapters, the military campaigns were brought together in separate chapters. These then became separated from the hadīth and specific books were written on them although the muhaddithin continued to include them within their chapters. So, in Bukhari there is the Book of Military Expeditions (kitab al-Maghazi) and in Muslim the Book of Jihad and Military Campaigns (kitab al jihad wa al-siyar).

Though many have written about the Sīrah, the first book that is existent from amongst the early compilers is the kitab al-Maghazi of Ibn Ishaq. Its author, Muhammad ibn Ishaq ibn Yassaar (d.153 A.H.) is considered the most well known of the ones who were associated with the maghazi, to the extent that Shafi'i is reported to have said: ' Whosoever wishes to be an expert in the maghazi, he should depend on Muhammad ibn Ishaq'. After Ibn Ishaq, the second early author is al-Waqidi. Muhammad ibn 'Umar ibn Waqid al-Waqidi (d.209 A.H.) was considered to have an extensive knowledge of the maghazi which approximated to that of Ibn Ishaq. He was very knowledgable in history and hadīth though it is reported about him that in later years he began to get his reports muddled. That is why many muhaddithin have branded him as weak, Bukhari says of him: ' His ahadīth are to be rejected (munkar al-hadīth)'. However they did not impugn the depth of his knowledge concerning the maghazi. Thus, Ahmad ibn Hanbal says about him: 'He is well-informed about the maghazi'. He has compiled a book on maghazi from which Ibn Saa'd quotes in his book al-Tabaqat (The Generations) in his discussion of the Sīrah. Likewise, Tabari also quotes from it. Two of the most famous compilers of the Sīrah are Ibn Hisham (d.218 A.H.) and Muhammad ibn Sa'ad (d.230 A.H.).

To this day Muslims have continued to devote their attention to the Sīrah. The Sīrah is considered one of the most important things to which Muslims should pay careful attention because it contains reports concerning the Messenger  in terms of his actions, sayings, silence and description; like the Qur’ān all of it is legislation. Therefore the Sīrah is one of the constituent elements of legislation and that is why it is considered part of the hadīth (literature). Whatever is proven to be authentic from it concerning the Prophet , in terms of its transmission and meaning, it is considered as a Sharī’ah evidence because it is from the Sunnah, not to speak of the fact that we are commanded by Allah  to emulate the Messenger . Allah  said:

Therefore, devoting ones attention to the Sīrah and its pursuance is a Sharī’ah matter. However, the difference between the method employed in compiling the Sīrah by the ancients and those who came in later periods is that: the method of the ancients in compilation of the Sīrah and history used to depend on the narration of reports. The historians started with the oral transmission; the first generation which witnessed the actions of the Messenger  or heard about it and transmitted it began to transmit it to others, the burden of which was assumed by the generation that came after. And some of them wrote down ahadīth in a miscellaneous manner which can be seen in the books of hadīth even today. Not till the advent of the second century (Hijri) do we find some scholars beginning to compile and put together the biographical reports and put them down in writing according to the method of narration, by mentioning the name of the transmitter and the one who transmitted from him, exactly as it was done in the (transmission) of hadīth. Thus, hadīth scholars and critics are able to know the authentic and acceptable biographical reports from the weak and inadmissible ones due to their knowledge of the transmitters and the chain of transmission. And this is the procedure which is relied upon when quoting from the Sīrah, as long as it is authentic, contrary to the modern authors of the Sīrah who only enumerate events without mentioning their transmitters. That is why their books are not relied upon as a source of Sīrah except when the author verifies at the time of writing that the transmitted reports are indeed from the Sīrah reports and are trustworthy. If he does not then his statement is not quoted but the event which he mentions is traced back to the books of Sīrah which have been transmitted according to the method of narration or to the books of hadīth. This is because reports concerning the Prophet  from the Sunnah are not taken except when they are authentic.

There is another area the historians have attended to, in addition to their approach to the Sīrah and that is the historiography of the Islamic events in relation to wars between some Muslims and wars between the Muslims and other nations and the subsequent conquests and events that followed. A group of historians became well known (for this approach), the foremost amongst them being Abu Mikhnaf Lut ibn Yahya ibn Sa'id ibn Mikhnaf ibn Salim al-Izdi (d.170A.H.). Some of the most famous books written by him are; The Conquest of al-Sham (futuh As-Sham), Conquest of Iraq (Futuh Al-Iraq), al-Jamal, Siffin and the murder of Hussayn Maqtal Al Hussayn). It is apparent that each book is a commentary on a particular issue. Nothing remains from the books that have been correctly attributed to him except that which Tabari has transmitted in his Tarikh (history). Many muhaddithin have discredited him by saying that he used to narrate from a group of unknown transmitters (majhulin). Among the famous historians is al-Mada'ini. He is 'Ali ibn Muhammad al-Mada'ini (d.225 A.H.), a prolific author. He wrote books concerning reports about the Prophet  and Quraysh. He also wrote books about reports concerning women and about the Khulafa. Tha'lab al-Nahawi described him thus: 'Whosoever wishes to know the reports concerning the Days of Ignorance he should consult the books of Abu 'Ubayda, and whosoever wishes to know about the reports concerning Islam let him consult the books of al-Mada'ini'. Also, the muhaddithin have not questioned his probity. Yahya ibn Ma'in, one of the most famous rijal critics says he is trustworthy (thiqa).
