Ghurūr: Being fooled
Al-Ghazali wrote a whole book on ghurūr, the easy confidence that you are fine when you are not. Someone with money and standing reads those things as a verdict on their own worth, and nothing nearby argues back. The confidence holds up until the person arrives somewhere that money and standing cannot follow.
Be in the world like a stranger or a traveler passing through: nothing here is home
The Prophet said this to a companion, and it describes how anyone treats a hotel room. Nobody in a hotel argues about the curtains, because the arrangement has an end date built into it. A person living that way still enjoys the house and the car, but stops treating them as the floor underneath.
Dhikr al-mawt: Keeping your own death in view
Al-Ghazali closes the Revival with dhikr al-mawt, and most people hold their own ending the way they hold a statistic about strangers. Someone who keeps it in view for a minute finds things sorting fast: the argument they meant to win shrinks, the call they postponed moves up. Doing this does not darken a life; it makes a person honest about how much time is left.
Die before you die: the letting go happens first
Sufis repeat this line constantly, and the dying they mean is a loosening of the grip on being someone, on winning, on being owed. Whoever loosens early does it on their own terms, and whoever waits has the grip opened for them later. It looks like handing back what you counted as yours while you still have a say in it.
The world is a prison for the believer and a paradise for the one who denies: comfort proves nothing
The Prophet said this, and it cuts in both directions. One person's best days are happening right now, another's are cramped and slow, and neither situation reports who is doing well. The saying keeps comfort from working as evidence, so an easy life stops counting as proof that someone got it right.
Everything perishes except His Face: one thing does not wear out
The Quran says this. Looks, strength, and a good name are on loan and wear out on a schedule nobody controls, which anyone who has watched something beautiful get old already knows. The other half of the line points at what stays, so a person has somewhere steady to rest their weight.
