Da'wah to Islam is an important aspect of our religion. Allah, subhanahu wa ta`ala, said, "Say (O Muhammad SAW): "This is my way; I invite unto Allâh (i.e. to the Oneness of Allâh - Islâmic Monotheism) with sure knowledge, I and whosoever follows me (also must invite others to Allâh i.e to the Oneness of Allâh - Islâmic Monotheism) with sure knowledge. And Glorified and Exalted be Allâh (above all that they associate as partners with Him). And I am not of the Mushrikûn (polytheists, pagans, idolaters and disbelievers in the Oneness of Allâh; those who worship others along with Allâh or set up rivals or partners to Allâh)." (Yusuf 12:108). Allah, subhanahu wa ta`ala, also said, "And who is better in speech than he who [says: "My Lord is Allâh (believes in His Oneness)," and then stands straight (acts upon His Order), and] invites (men) to Allâh's (Islâmic Monotheism), and does righteous deeds, and says: "I am one of the Muslims." (Fussilat 41:33)"
