Narrated Ibn 'Umar (RA):

The Prophet (ﷺ) forbade selling a debt to be paid at a future date for another i.e., a debt for a debt. [Reported by Ishaq and al-Bazzar with a Da;if (weak) chain].

وَعَنِ اِبْنِ عُمَرَ ‏-رَضِيَ اَللَّهُ عَنْهُمَا‏-; { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-نَهَى عَنْ بَيْعِ اَلْكَالِئِ بِالْكَالِئِ, يَعْنِي: اَلدَّيْنِ بِالدَّيْنِ } رَوَاهُ إِسْحَاقُ, وَالْبَزَّارُ بِإِسْنَادٍ ضَعِيفٍ [1]‏ .‏
