(إِعْطَاءُ شَيْءٍ زَائِدٍ عِنْدَ إِرْجَاعِ القَرْضِ أَفْضَلُ)
(Giving something extra when repaying a loan is better)
Hadith 2925
وَعَنْ جَابِرٍ قَالَ: كَانَ لِي عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَيْنٌ فَقَضَانِي وَزَادَنِي. رَوَاهُ أَبُو دَاوُد
Jabir said the Prophet owed him a debt and gave him something extra when he paid it. Abu Dawud transmitted it.
