From Ruba`iyat-i Khayyam (my translation) (But don't expect much Persian translations from me, as it takes me forever):
"If we came respectful to the mosque,
we did not come to attend to
the requirements of prayer;
But we had stolen a carpet*,
and to replace the old one
we came again"
(He used sajjade as in the Arabic Sijjadah, which here means prayer rug)
