Nafs al-ammāra: The self that pushes a person toward wrong
The Quran names a self in everyone that keeps steering toward whatever it wants. Its favorite cover is loud disapproval of someone else, since the noise of a verdict drowns out the same appetite working quietly at home. A person can spend years listing other people's failings and stay perfectly comfortable, never once looking at the same pull in themselves.
Arrogance is rejecting the truth and looking down on people: what pride does
The Prophet described pride that way. Both halves show up together: once someone looks down on a person, they can no longer hear anything that person might tell them about themselves. Feeling above others is comfortable, and the comfort is what keeps a fault sitting in place for years.
A sin that leaves you humble beats an obedience that leaves you proud: what a clean record can cost
Ibn Ata Allah put it in those words. Someone keeping score has usually done the things on their own list, and that record is what makes them feel entitled to sentence anyone else. The person who fell knows exactly where they stand, and that plain knowledge is worth more than a spotless record that has made its owner hard.
Muḥāsaba: Taking account of yourself
Al-Ghazali set aside time each day for this, the way a shopkeeper goes over the day's takings. The attention that was busy with someone else's behavior turns around and reviews a person's own past week instead. The account usually comes out worse than expected, and that sting ends the habit of ranking people faster than any argument.
Whoever hides another's fault has his own hidden: what to do with what you see
The Prophet promised that. Seeing a flaw in someone leaves a person at a fork: pass it around, or hold it quietly. Passing it on feels like fairness at the time, though it mostly trains someone to meet every failing, their own included, by dragging it into the open.
Ḥusn al-ẓann: Thinking the best of people
The Quran warns against running on suspicion, and Sufis made a habit of the kindest reading that fits the facts. Anyone passing judgment is usually working from a scrap: one remark, one bad afternoon, no idea what came before it. The better explanation costs nothing, is right more often than not, and removes the ground the whole verdict was standing on.
