It is also said that a scholar of 13th century A.D. Ibn Shahrashub-al-Mazoarani had a thousand books with the title "Munaqib" (Noble virtues) in his library all written about Ali (A.S.).
It is significant to note that the sources from which the material has been collected on Ali (A.S.) or about Ali (A.S.) and his family and friends has been the sources that were too far from them. They did not have any direct or close relations with Ali (A.S.) or his relatives, descendants friends and their relations. The government had so terrorized the people that nobody dared to go near the descendants of the Prophet (S.A.W) or Ali (A.S.). Imam Bukhari who had the privilege of living at a time when four of the greatest descendants of the Prophet (S.A.W) viz, Imam Ali Ibne Moosa Ar Reza, Imam Mohammad Taqi, Imam Ali Naqi and Imam Hasan Askari (peace be on them all) were living but he did not consult them or even see them. Though it is said that he travelled throughout the world and met each and every person who could give him some material on the life and activities of the Prophet (S.A.W), his relatives and friends. Even the friends of Ali (A.S.) and their descendants were prevented from taking any information from them [Al-Fiqah by Maulana Umar Kareem]. The same attitude was adopted by other traditionalists like Muslim, Abi Dawood, Tirmizi, Nisai and Ibne Majah who too lived during the same period but never referred to the Prophet (S.A.W)s descendants. Hafiz Bin Asaakir has mentioned a list of all such great writers who avoided meeting the family members of the Prophet (S.A.W) and their descendants. [Minhajus Sunnah of Ibne Taimia, page 121). Even then so much has been said of him and yet so little. His pragmatic personality presents a fresh hue to every one who wants to see at him and find him. Let us also search for this serene soul, this moving spirit of Islam, this bright star in the sky of humanity.
