Hawzah News Agency – Imam al-Sadiq peace be upon him says:

السَّخاءُ مِن أخلاقِ الأنبياءِ، وهُو عِمادُ الإيمانِ، ولا يكونُ مؤمنٌ إلّا سَخيّاً، ولا يكونُ سَخيّاً إلّا ذو يَقينٍ وهِمَّةٍ عالِيَةٍ؛ لأنَّ السَّخاءَ شُعاعُ نورِ اليَقينِ، ومَن عَرَفَ ما قَصَدَ، هانَ علَيهِ ما بَذَلَ.

'Generosity is one of the noble traits possessed by prophets. It is the pillar of belief, such that only a true believer will be generous, as well as one who possesses great certainty and high aspiration, for generosity is a gleam from the light of certainty, and the one who knows what he wants finds it easy to give away.'
