What are the simple, concise, and age-appropriate books for 11-15 year olds that help teach the biography of the Prophet (peace be upon him) and the Companions, assist the teacher in imparting manners and ethics, and include Islamic educational methods?

The best of people are those who learn the Qur'an and teach it, and this includes learning its letters and meanings. There are many useful references for teaching the Qur'an, the Sira (Prophet's biography), and the lives of the Companions. Among the suggested books for teaching the Qur'an are: "Teaching Skills in Qur'anic Circles," "Qur'anic Schools and Kuttab: Educational and Administrative Insights," "The Art of Supervising Qur'anic Circles and Institutions," "Reflections for the Teacher of the Holy Qur'an," "My Circle is Special," and "Al-Tibyan fi Adab Hamalat Al-Qur'an" (The Exposition on the Etiquette of the Bearers of the Qur'an). For teaching the Prophet's Sira, one can benefit from "The Sira of the Prophet - Level One" by Zad Academy, the approved Sira curriculum in Saudi Arabia, and the books "Learn from the Greatest Teacher Muhammad, peace be upon him" and "My Teacher Muhammad, peace be upon him." As for the lives of the Companions, one can benefit from "Pictures from the Lives of the Companions," "Biographies of the Geniuses among the Companions and Tabi'in," "The Delight of the Eyes with the Relics of the Companions and Tabi'in," and "The Golden Encyclopedia for the Muslim Child."
