189. They ask you concerning the new moons. Say, "They are but signs to mark fixed periods of time in men and for the Hajj." It is no virtue if you enter your houses from the back: it is virtue if you fear God. Enter houses through the proper doors, and fear Allah, that you may prosper.
(The Heifer 1:189)
