Narrated Abu Huraira:
حَدَّثَنَا إِسْحَاقُ ، أَخْبَرَنَا عَبْدُ الرَّزَّاقِ ، أَخْبَرَنَا مَعْمَرٌ ، عَنْ هَمَّامٍ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " كُلُّ سُلاَمَى مِنَ النَّاسِ عَلَيْهِ صَدَقَةٌ، كُلَّ يَوْمٍ تَطْلُعُ فِيهِ الشَّمْسُ يَعْدِلُ بَيْنَ النَّاسِ صَدَقَةٌ " .
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."
