At the advent of Satar (seclusion), salatin of Hamdan, under the leadership of Sultan Hatim ibne Ahmed ibne Imran Al-Yaami were the rulers of Sana. Syedna Al-Mukarram had appointed Al-Imran ibne Fazal Al-Yaami his deputy on Sana when he shifted his capital from Sana to Zi-Jibla and deposed him after some time, but his son Sultan Hatim dominated over Sana'a in 533 AH after the sad demise of Maulatona Al-Hurrat Al-Malikah (a.q.). Banu Zari were the rulers of Aden. Syedna Mukarram had appointed the two brothers Abbas and Masud as his deputies over Aden. Banu Zari annexed Taiz, Janad, and Zi-Jibla to their rule after the sad demise of Maulatona Arwa. Banu Mahdi were in Zabid who captured Taiz, Janad, and Zi-jibla after some period removing Banu-Zari. These clans remained as the rulers of the these regions till the domination of Banu Ayub over Yemen in 569 AH.
Study of history reveals that Satar is not only an important juncture in the history of Dawat, but, in the history of world also as far reaching changes took place in political, economic and intellectual fields around the that period At the advent of 'Satar' Islamic world was facing many serious challenges due to different internal and external adverse forces. Crusaders of Europe with the help of Byzantine empire of Asia Minor were attacking on Islamic world. They had captured Bait ul Maqdis and established four christian states on the eastern coast of Mediterranean sea. Not only this, they were trying to convert Muslim world into christian world. Abbasids, due to their insincerity to the cause of Islam, incompetency of their so-called caliphs and their internal problems, were unable to defend Islamic world. Abdul-Majid, the usurper of the seat of Fatimi Khilafa in Egypt was also unable to face this challenge. Nooruddin Zanji, the ruler of Syria tried to contain the advancement of crusaders and he defeated them in second crusade (1147-1149 AD). Crusade wars provided Europeans an opportunity to unit, to strenghten their military power, to observe the cultural development of Muslim world. These wars became a pretext to European renaissance in intellectual field, merchantilism in economic field, and colonisation in political field. Genghis Khan, the terrible Mongol chief who destroyed much of the eastern part of Muslim world and slaughtered lakhs of people was born after only a few years from 'Satar' of Imam.
During this period of turmoil, Yemen, because of it's geographical isolation and it's hilly regions, was relatively a safer abode for Doat Kiram and their followers and a better place for the spread of guidance and knowledge.
