I believe the answer is:
ramadan
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">month of fasting for muslims</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for ramadan that I've seen before include "Moslem fast" , "Islam's holiest month" , "Islamic holy month" , "Month of fasting from dawn to dusk" , "lunar month" .)
