(12) O you who have believed, when you [wish to] privately consult the Messenger, present before your consultation a charity. That is better for you and purer. But if you find not [the means] - then indeed, Allah is Forgiving and Merciful. (13) Have you feared to present before your consultation charities? Then when you do not and Allah has forgiven you, then [at least] establish prayer and give zakah and obey Allah and His Messenger. And Allah is Acquainted with what you do.
