It was your Lord who put an end to long-windedness, so that you would not pray as if you wanted to teach God by your many words. Piety, not verbosity, is in order when you pray, since He knows your needs. Now someone perhaps will say: 'But if He knows our needs, why should we sate our requests even in a few words? Why should we pray at all? Since He knows, let Him give what He deems necessary for us.' Even so, He wants you to pray so that He may confer His gifts on one who really desires them and will not regard them lightly.
