Allah made Da'awa Fardh on all the Muslims. To show us how to do it, He sent His Anbiya. And told His Nabi Muhammad(SAWS) to follow their way. So the way of Rasoolullah(SAWS) is not only the best way in every phase and aspect of life but most of all in the purpose for which he was sent, Da'awatul Islam. Today in our anxiety to take the message of Islam to the world we tend to disregard the basic principles of this work and get caught up in Western concepts and lose our very identity as Muslims. Some have been so confused as to make Da'awa a means of earning their own livelihood which goes against the very spirit of Islam and against the single most critical differentiator; the common factor of every Nabi that Allah mentioned more than ten times in the Qur'an. Yunus 10:72], Hud 11:51], Hud 11:29], Shu'ara 26:127], Shu'ara 26:109], Shu'ara 26:145], Shu'ara 26:164], Shu'ara 26:180], Saba' 34:47], An'aam 6:90]. This booklet attempts to emphasize the importance of Da'awa and of following the Sunnah in doing it so that we are not deprived of the Baraka of this greatest of human endeavors - to save all mankind from the anger of Allah. We ask Allah for His Pleasure.
