Sayf ibn Umar's Fake Reports in Westerners' Shiite Studies

Investigating the sources of the history of Islam is among the interesting topics by the orientalists. However, some of them have ignore this and refer to and exaggerate some fake reports from falsifiers such as Sayf ibn Umar and try to portray a fake and unreal illustration from the Shiite. The main research question here is that what position do Sayf ibn Umar's reports have taken in the westerners' Shiite studies? This writing has investigated and evaluated some orientalists' research and their citations to Sayf ibn Umar reports. It is proven that these research are in contradiction with each other in using Sayf ibn Umar's reports and the influential factors on his historical directions. Thus, orientalists have not acted the same in citing Sayf ibn Umar's reports. They have been doubtful some times and have denied these reports in whiles or have approved them on some occasions. However, they have deemed valid Sayf ibn Umar's reports on the advent of Shiite and accordingly have believed that Shiite ideology has been the cause of division and sedition in the Islamic community. Likewise, they have introduced it as the result of religious change of thought which is affected by the environmental and cultural factors of Iraq.
