they ask you about the phases of the moon. say these are signs for the people to reckon dates and fix the periods for hajj. also tell them it is no virtue to enter your houses from their backs during the hajj days) real virtue is that one should refrain from incurring the displeasure of allah so enter your houses by their proper doors. and fear allah so that you may gain success.
