Tafakkur literally means to think on a subject deeply, systematically, and in great detail. In this context, it signifies reflection, which is the heart’s lamp, the spirit’s food, the spirit of knowledge, and the essence and light of the Islamic way of life. Reflection is the light in the heart that allows the believer to discern what is good and evil, beneficial and harmful, beautiful and ugly. Again, it is through reflection that the universe becomes a book to study, and the verses of the Qur’an disclose their deeper meanings and secrets more clearly. Without reflection, the heart is darkened, the spirit is exasperated, and Islam is lived at such a superficial level that it is devoid of meaning and profundity.
