The Rubaiyat By Omar Khayyam III

 And, as the Cock crew, those who stood before
The Tavern shouted--"Open then the Door!
You know how little while we have to stay,
And, once departed, may return no more."

 وقت سحر است خيز اي مايه ناز
اندک اندک باده خور و چنگ نواز
کانها که بجايند نپايند بسي
و آنها که شدند کس نمي آيد باز
