Actions are by Intention, as long as it is Correct

Ibn `Ijlaan said, "the action is not acceptable except by three: Taqwaa of Allaah, and good intention, and correctness (i.e. conformity to the Sunnah)"

[reported by ibn Abee ad-Dunyaa in his ‘al-Ikhlaas wa an-Niyyah', found in 'The Hadeeth of Intention']
