Al-Ghazali on Vigilance and Self-examination is the thirty-eighth chapter of the Revival of the Religious Sciences and follows on from Al-Ghazali on Intention, Sincerity & Truthfulness. Here Ghazali focuses on the different stations of steadfastness in religion (murabata), vigilance and self-examination being its cornerstones. As in all his writings, Ghazali bases his arguments on the Qur'an, the example of the Prophet and the sayings of numerous scholars and Sufis.
