Hadith 8:191
Abu Umama told of hearing God's Messenger say, “A loan must be paid back, a minha * must be returned, a debt must be discharged, and one who stands surety is held responsible.” Tirmidhi and Abu Dawud transmitted it. *This may be a she camel lent for a time for milking, but it can be used of other things which are lent for some specific purpose.
وَعَنْ أَبِي أُمَامَةَ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «الْعَارِيَةُ مُؤَدَّاةٌ وَالْمِنْحَةٌ مَرْدُودَةٌ وَالدَّيْنُ مَقْضِيٌّ وَالزَّعِيمُ غَارِمٌ» . رَوَاهُ النرمذي وَأَبُو دَاوُد
