With all humility...
With all humility, the author hopes this book will be considered as the foremost among such works. It is well known that love and affection for the family of the infallibles and pure ones (Ahle Bayt (a.s.)) is incumbent on the Muslim Ummah. Hence, it is our most important duty to know the conditions and the history of events connected with this pious household (a.s.). It is highly regrettable that, until now, what is going on is quite the opposite.
That is, the Islamic scholars, who have compiled huge tomes on various subjects, have made no contribution to the history of Ahle Bayt (a.s.) whose love and affection is the basic and important condition for true faith. For instance, many works have been published on the history of Samanids, Seljuks, Buwayhids, Ottomans, etc. but we have no book on the history of the Aale Muhammad (s.a.w.s.). Is this not a matter of shame and regret?
The Muslim scholars have not paid more attention to any science other than history and the transmission of events. The works of Ibne Khaldun, Ibne Athir, Ibne Khallekaan, Masoodi and other well-known scholars are the best examples of the science of narration and history. The best examples of the extraordinary importance given by Muslim scholars to such narration and history are History of Damascus by Ibne Asaakir in fifty volumes and History of Baghdad by Khateeb-e-Bagdadi in eighty volumes.
In the field of narration too, we have works like Osodul Ghaabah. Also, some of the valuable works have been side tracked despite their importance. In spite of all these works of great importance what is regrettable is that the history of the Holy Prophet's (s.a.w.a.) progeny has not received any serious attention. Historians have not paid as much attention to Imam Reza (a.s.) as they have given to Mutanabbi (a false prophet). It has paid more regard to Abu Yusuf than to Imam Moosa Kazim (a.s.).
If prejudice is set aside and the matter is looked into impartially, what will appear is quite the opposite. If somebody claims otherwise, the pages of history would readily support the truth. It is very regretful that a well-known historian like Tabari, in his famous Tarikh, does not given importance to some really important events and regards them as unworthy of mention.
He does not utter even a few words in favour of the established rights of the Holy Progeny of the Prophet (s.a.w.s.) but discusses worthless things like Nimrud riding a vulture, which raises him, high towards the sky!
