Imam Qushayri (Allah have mercy upon him) relates in his Risala that Yahya ibn Mu`adh al-Razi (Allah have mercy upon him) said,
“Three matters are from the traits of the elect (awliya’):
1. Confidence in Allah in all affairs.
2. Sufficiency with Allah from all else.
3. Returning to Allah from all things.”
And Allah alone gives success.
