Musannaf Ibn Abi Shaybah 37719 — Yahya bin Jadah

It is narrated from Abu Awn that he said: When the people of goodness met one another, they would advise one another with three things, and when they were absent they would write these to one another: Whoever works for his Hereafter, Allah Almighty suffices him for his world. Whoever keeps right what is between himself and his Allah, Allah Almighty suffices him against the people. Whoever keeps his private life right, Allah Almighty sets his public life right.
