HAFEZ
دور گردون گر دو روزی بر مراد ما نرفت، دائماً یکسان نباشد حال دوران غم مخور
Dowr-e gardun gar do ruzi bar morâd-e mâ naraft, dâ'emân yeksân nabâshad hâl-e dowrân, gham makhor
If the wheel of fortune ran against us for a few days, do not grieve — the state of the age never stays the same.
Hafez · Divan, Ghazal 255
