Sadaqah
Ṣadaqah (Arabic: صدقة [ˈsˤɑdæqɑ],* "charity", "benevolence", plural ṣadaqāt صدقات [sˤɑdæˈqɑːt]) in the modern-day Islamic context has come to signify "voluntary charity". Unlike zakat, which is an obligatory form of almsgiving and one of the five pillars of Islam, ṣadaqah is a voluntary offering whose amount and nature are determined solely by the benefactor, as emphasized in the Quran.
