كتاب البيوع
Read the English translation first, with the original Arabic directly underneath.
Narrated AbuMusa al-Ash'ari:
The Prophet (ﷺ) said: After the grave sins which Allah has prohibited the greatest sin is that a man dies while he has debt due from him and does not leave anything to pay it off, and meets Him with it.
إِنَّ أَعْظَمَ الذُّنُوبِ عِنْدَ اللَّهِ أَنْ يَلْقَاهُ بِهَا عَبْدٌ - بَعْدَ الْكَبَائِرِ الَّتِي نَهَى اللَّهُ عَنْهَا - أَنْ يَمُوتَ رَجُلٌ وَعَلَيْهِ دَيْنٌ لاَ يَدَعُ لَهُ قَضَاءً
