قال ابن المبارك: " رُبّ عمل صغير تُكثّره النية ورُبّ عمل كثير تصغره النية ".
(8/400)
Al-dhahabee reports in the 'siyar' than Ibn Al-mubaarak stated " How many deeds few in number have become many by way of the niyyah (intention) and how many deeds great in number have been made insignificant due to a (faulty) intention".
