From AhlusSunna
By Imam an-Nawawi
The principles of tasawwuf’s signs on a person are also five:
1. Seeking Sacred Knowledge in order to perform Allah’s command;
2. Keeping the company of shaykhs and fellow disciples (murids) in order to see with insight;
3. Foregoing both dispensations from religious obligations and figurative interpretations of scripture, for the sake of cautiousness;
4. Organizing one’s time with spiritual works to maintain presence of heart; and
5. Suspecting the self in all matters, in order to free oneself from caprice and be safe from destruction.
