What is the best way to teach a new revert to Islam, and what books or websites are available in Tagalog or English that can be useful for this purpose?

Congratulations to you for guiding someone to Islam through your hands, for this is better for you than red camels. After his conversion to Islam, instruct him to perform ghusl (ritual bath) and prayer, help him memorize Al-Fatihah, and teach him prayer and purification practically. Explain to him the meaning of the word of Tawhid (Oneness of God), its conditions, and its virtues (entering Paradise and salvation from Hellfire). You can give him a copy of "The Three Fundamental Principles" translated into English. Refer to the Dawah Center for Communities in Jeddah or the offices of the Center for Dawah and Guidance for assistance, as they may have Filipino callers and translated books.
