And remain in your houses with grace and dignity (you being the mothers of the believers will not be allowed to merry) and do not show yourselves off as (did the women) in the bygone days of ignorance (who displayed their finery), and observe Prayer, present the Zakât (- the purifying dues) regularly and obey Allâh and His Messenger. Members of the house (of the Prophet of God)! verily, Allâh desires to rid you of (all) uncleanliness and to purify you completely.
