Chapter on the Virtue of Charity
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 1|Chapter 20
وَ قَالَ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ: «اَلصَّدَقَةُ بِعَشَرَةٍ وَ اَلْقَرْضُ بِثَمَانِيَةَ عَشَرَ وَ صِلَةُ اَلْإِخْوَانِ بِعِشْرِينَ وَ صِلَةُ اَلرَّحِمِ بِأَرْبَعَةٍ وَ عِشْرِينَ.
The Messenger of Allah سبحانه وتعالى, peace and blessings be upon him and his family, said: "Charity is rewarded tenfold, a loan eighteenfold, kindness to brothers twentyfold, and maintaining ties of kinship twenty-fourfold."
