Is it permissible to give books to Christian people if these books contain Ayahs (Qur'anic verses) showing Tawhid (monotheism) that are written in Arabic and translated into English?
Yes, it is permissible to give them books that contain Ayahs that stand as proof of certain rulings such as Tawhid and other issues, whether or not they are written in Arabic or translated into English. This act is appreciated and the doer will be rewarded if he has a sincere intention. Moreover, giving or lending people such evidence is regarded as a kind of notification and Da`wah (Call to Islam).May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
