Ṣuḥba: Companionship with a guide
Ṣuḥba names the long companionship between a seeker and someone further along the road. A person cannot watch their own habits from the outside, and the parts that most need work are usually the ones hidden from them. Al-Ghazali compared such a guide to a doctor, since an illness you cannot see in yourself still needs treating by someone who can.
Naṣīḥa: Wanting good for someone and telling them
The Prophet said that religion itself is naṣīḥa, wanting good for people and saying it plainly. Honest words about a person's faults cost the one who speaks them, because almost nobody says thank you in the moment. When a person grasps that a correction was expensive to give, it stops landing like an attack.
Every one of you is a shepherd, and every one is answerable for the flock: leading means answering for people
A saying of the Prophet puts each person in charge of someone and on the hook for them. From underneath, authority looks like comfort and rank; from inside, it feels like a debt that keeps coming due. Once the weight on that side is clear, going along with a leader feels less like losing ground and more like helping carry something.
Taslīm: Handing yourself over
Taslīm means handing yourself over to the direction you have been given. The hard moment arrives when an instruction makes no sense and your own reasoning looks better. Keeping a private veto in your pocket turns guidance into an argument you win every time, and putting that veto down is what lets anyone teach you.
Adab: Courtesy in how you deal with a teacher
Adab covers the small courtesies: tone, timing, not making things harder than they need to be. Two people can follow the same instruction, one with a sigh and one with warmth, and the difference lands squarely on the person leading. Grudging cooperation wears a teacher down until they hold back what they know, and the student is the one who loses.
