These six Imams are unanimously agreed upon as the leaders of The Ummat (the community of The Messenger of Allah Sallallahu Alaihi Wasallam). The Imams of Mad’habs formed their Mad’habs by strictly following Qur’an and Sunnah. They never held an opinion which is against the interest of the two main sources of Islam. All their researches were scrutinizing the inner and outer meanings of the Qur’an and Sunnah. They were more learned and with dazzling intelligence and memory power, irrespective of the lack of modern facilities of learning. Even Ibnu Taimiyya (The one who paved the way for the all innovators who came after him till the present day. All the factions, though with apparent differences in approaches, trace to their common ancestor Ibnu Taimiyya) emphasized the greatness of the Imams of Mad’habs who lived and died even before the compilation of the famous collection of the Ahaadeeth by the great Muhadditheen like Imam Bukhari and Imam Muslim and the like. Take the words of Ibnu taimiyya “Those who came before the compilation of the Hadeeth books, were more knowledgeable with Qur’aan and Sunnah than those who came later”.
