(11) باب فَضْلِ الإِصْلاَحِ بَيْنَ النَّاسِ وَالْعَدْلِ بَيْنَهُمْ
Narrated Abu Huraira:
Allah's Messenger (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."
