Dhikr al-mawt: Remembering death
Al-Ghazali gave the closing part of his Revival to keeping death in mind. Someone who assumes more time is coming spends it loosely and pushes what matters to the far edge of the calendar. An ending with no announced date, held close, makes the hours weigh something while they are still in hand.
Everything perishes except His Face: only God lasts
Sufis return again and again to this line from the Quran. Anyone can feel the wobble in things they counted on: work, standing, health, the arrangements that seemed settled. The line sorts what was on loan from what stands, and leaves a person one thing to lean on.
Tajdīd al-khalq: Creation renewed at every instant
Ibn Arabi taught that the world is erased and remade at every instant, too fast for anyone to catch. Nothing a person holds is quite what it was a moment ago, so the ending being braced for has been running all along. That takes some of the dread out of it, since everyone has lived inside this pattern since birth.
Ikhlāṣ: Sincerity
Ikhlāṣ means doing something for God alone, with nothing else mixed in. Much of what people build has a second motive tucked inside: being seen, being praised, being counted as important. When everything is put to the test, the borrowed motive goes first, and only the part meant for God holds up.
Fanā': Passing away of the self
Sufis use fanā' for the self dropping out of the picture. A person dreading a great ending is usually dreading the end of themselves: the name, the story, the standing they have kept up. Those who have loosened that grip in advance find the fear has less to hold on to.
Baqā': Remaining in God
Baqā' names what is left once the self has passed away, a life carried by God rather than by the person. Total loss frightens people because they picture nothing at all on the other side of it. Sufis describe the losing as half the story; the life that remains no longer depends on holding itself up.
