This first volume of 'Presenting Islam in the West' sets out to present the methodology of the Call to Allah (ad-Da'wah ilallah) based on the Qur'an and Sunnah. The dai'i only calls to what he knows - following: "invite all to the way of your Lord (Islam) with wisdom and beautiful preaching, and reason with them in the best possible way (to convince them of the truth)." [Surah Nahl 16:125]. The caller gives information, Allah decides who becomes Muslim. Da'wah is invitational: not confrontational. The da'i's relationship to his listener(s) should be like that of a doctor and patient.
