Kibr: Pride
Pride starts with a comparison, and the tradition traces the first refusal to Iblis, who claimed he was made of better stuff. A person can be certain he is standing on God's side and still be running on that same claim underneath. Once someone counts as the better one in his own eyes, whatever he does to the person in front of him looks deserved.
Ḥasad: Envy
Envy wants what another has, and past a certain point it wants the other person gone; the tradition remembers that the first killing came from it. Al-Ghazali sets envy beside pride as the root that spoils everything else in a person. Nobody admits to it, so it surfaces as suspicion about the other's motives, then as a wish for his downfall dressed up as concern for what is right.
Waswasa: The whisper
The whisper arrives in a person's own voice. Because it sounds like his own thinking, he defends it as his and never asks where it came from. A thought he would refuse outright if a stranger said it out loud gets waved through when it seems homegrown.
Nafs al-ammāra: The self that urges toward harm
The Quran names a self inside a person that keeps pushing him toward what damages him. After enough years, he stops resisting the push and begins calling it his own taste. By then nothing is dragging him anywhere; he wants the thing, and the wanting feels like freedom.
Ghurūr: Self-deception
Al-Ghazali treats this as the last trap, the deception a person works on himself. A lie repeated often enough gets believed first by the one telling it, and after that he has no way back to solid ground. He can speak with complete confidence, sounding honest to his own ear, while none of it lines up with the facts.
Ṣidq: Truthfulness
Truthfulness here means the inside and the outside match, all the way down. Someone standing in that has nothing to guard, so he can take a hard word about himself and check whether it fits. Without it, every honest word from another person lands as an attack, and the answer is always to strike back instead of look.
