عن أبي أيوب قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَلا أَدُلُّكَ عَلَى صَدَقَةٍ يُحِبُّهَا اللَّهُ وَرَسُولُهُ تُصْلِحُ بَيْنَ النَّاسِ إِذَا تَبَاغَضُوا وَتَفَاسَدُوا

Abu Ayyub reported: The Messenger of Allah, peace and blessings be upon him, said, “Shall I not tell you of a charity beloved to Allah and his messenger? Reconcile people when there is hatred and corruption between them.”
