(I will also try to attach it.) % mwe % document is an English translation of Arabic text; all annotations are in English. % % concerning footnotes to Arabic text: % numbers in body should use Mashriki numbers (e.g. ٠١٢٣٤٥٦٧٨٩), and appear between parenthesis % numbers in footer should use Arabic numbers (e.g. 0123456789), and without parenthesis % % MWE uses dejavu for English and Amiri for and Arabic.
