Turn thee from grief nor care a jot,
Commit thy needs to fate and lot,
Enjoy the present passing well,
And let the past be clean forgot.
For what so haply seemeth worse
Shall work thy weal as Allah wot;
Allah shall do whate’er he will,
And in his will oppose him not.
Alf Laylah wa Laylah
(Burton’s “Arabian Nights”).
