And remain in your houses with calm and peace and do not display adornment like that of the days of ignorance and establish Prayer and pay Zakat (the Alms-due) and keep obeying Allah and His Messenger (blessings and peace be upon him). Allah intends only to remove all impurity of sins from you, O People of the House (of the Prophet, [even a doubt or trace of shortfall,]) and make you absolutely pure and clean by blessing you with (perfect) purity and wholesomeness.
