Messenger of Allah ﷺ said, "There is a Sadaqa to be given for every joint of the human body; and for every day on which the sun rises there is a reward of a Sadaqa (i.e. charitable gift) for the one who establishes justice among people."  

قَالَ رَسُولُ اللَّهِ ﷺ كُلُّ سُلاَمَى مِنَ النَّاسِ عَلَيْهِ صَدَقَةٌ كُلَّ يَوْمٍ تَطْلُعُ فِيهِ الشَّمْسُ يَعْدِلُ بَيْنَ النَّاسِ صَدَقَةٌ
