Who is this attributed to and could you please mention the reference and Arabic text?
“Behave well in your private life and Allah will make your public life excellent. Take care of what is between you and Allah, and He will take care of what is between you and the people. Work for the Hereafter and Allah will suffice your affairs in this world.”
Imam Abu Nu’aym (rahimahullah) has recorded this as the statement of Sufyan Thawri (rahimahullah).
(Hilyatul Awliya, vol. 7 pg. 35)
أحسن سريرتك يحسن الله علانيتك وأصلح فيما بينك وبين الله يصلح الله فيما بينك وبين الناس واعمل لآخرتك يكفك الله أمر دنياك
