"During the year of the Farewell Pilgrimage, I heard the Prophet ﷺ saying during the Khutbah: "The borrowed is to be returned, and the guarantor is responsible, and the debt is to be repaid."  

[Abu 'Eisa said:] There are narrations on this topic from Samurah, Safwan bin Umayyah, and Anas. [He said:] The Hadith of Abu Umamah is a Hasan Gharib Hadith. It has also been reported through other routes besides this, from Abu Umamah, from the Prophet ﷺ.
الترمذي:١٢٦٥حَدَّثَنَا هَنَّادٌ وَعَلِيُّ بْنُ حُجْرٍ قَالاَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَيَّاشٍ عَنْ شُرَحْبِيلَ بْنِ مُسْلِمٍ الْخَوْلاَنِيِّ عَنْ أَبِي أُمَامَةَ قَالَ

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ فِي خُطْبَتِهِ عَامَ حَجَّةِ الْوَدَاعِ الْعَارِيَةُ مُؤَدَّاةٌ وَالزَّعِيمُ غَارِمٌ وَالدَّيْنُ مَقْضِيٌّ  

قَالَ أَبُو عِيسَى وَفِي الْبَابِ عَنْ سَمُرَةَ وَصَفْوَانَ بْنِ أُمَيَّةَ وَأَنَسٍ قَالَ وَحَدِيثُ أَبِي أُمَامَةَ حَدِيثٌ حَسَنٌ وَقَدْ رُوِيَ عَنْ أَبِي أُمَامَةَ عَنِ النَّبِيِّ ﷺ أَيْضًا مِنْ غَيْرِ هَذَا الْوَجْهِ
