Niyyah
Niyyah (Arabic: نِيَّةٌ, variously transliterated niyyah, niyya [ˈnij.jah], "intention") is an Islamic concept: the intention in one's heart to do an act for the sake of God (Allah). The general Islamic principle of niyyah is laid out in Chapter 33 (Al-Ahzab) of the Quran in Ayat (Verse) 5: There is no blame on you for what you do by mistake, but (only) for what you do intentionally.
