O you who believe ! let those whom your right hands possess and those of you who have not attained to puberty ask permission of you three times ; before the morning prayer , and when you put off your clothes at midday in summer , and after the prayer of the nightfall ; these are three times of privacy for you ; neither is it a sin for you nor for them besides these , some of you must go round about ( waiting ) upon others ; thus does Allah make clear to you the communications , and Allah is Knowing , Wise .
