" It is no coincidence that those very people who do good and who hope to do more of it are, in fact, those who reflect on death and work for the Hereafter the most, so that the Day of Judgment will be a moment of joy and light for them. It is wise to meditate on death— its throes and the various states after it. For example, one should imagine—while he or she has life and is safe—the trial of the Traverse (al-ṣirāṭ) that every soul must pass over in the Hereafter, beneath which is the awesome inferno and the screams and anguish of those evildoers who already have been cast therein. "
