intention / purpose
Feminine noun. From نَوَى (to intend). Plural: نِيَّاتٌ (niyyāt). While the word itself appears rarely in the Quran, the concept permeates Islamic law and ethics.
The Prophet ﷺ said: 'Actions are but by intentions' (innamā al-aʿmālu bin-niyyāt) - perhaps the most quoted hadith, making niyyah the foundation of all deeds.
