Risale-i-Nur is a collection of works written as a tafsir on the Qur'an and as a reflection on Islamic values from the early to mid twentieth century by Kurdish-Turkish theologian, renowned for his vast intellect and humility, and endurance in the face of tyranny and oppression, Said Nursi, who earned the title "Badiuzzaman" or "master of our times", revived Islam in Turkey for generations to come, and urged the importance of Islamic values in the face of growing Western materialism and the ideologies associated with scientific materialism, atheism, and communism. He urged the mixing of science and rationality with spirituality, and his entire works, exceeding 5 thousand pages, are now available in English as an app on the google play store (I believe they may be available on other app stores for mobile phones as well). It is well worth reading.
