Islam was descended upon the humanity through our beloved Prophet Salallaho Alihe Wa Aalihee Wasallam to rule the minds and hearts of every mankind. Few adopted the teachings and commandments of easily and on some it was enforced forcefully.
For over 1200 years or so, the Muslim world witnessed a peak of prosperity and advancement in the history of mankind. Islam had influence in almost every nook and corner of the world, the reason behind the cause were several.
The Muslims in the past feared Allah, the Creator of this world, the entire universe and the hereafter. They possess true faith, endless love for their Prophet S.A.W, having political shrewdness and dignity of Muslims in mind. They care for the pleasure of Allah then any other. They give prime importance to their Namaz and other obligatory and recommended practices of Islam. Live their lives with simplicity whether they were the rulers or the ordinary men. In short, they abandoned their lives for the sake and pleasure of only Allah.
Unlike now, when the so called Muslims are in a race with others to achieve unlimited material gains in their short lives, giving least importance to the criterion of Haram and Halaal given by Islam. A Muslim of today run for women, want to spend high-fi lives, loves music, films and other entertainment stuff.
