ثُمَّ يَوْمَ ٱلْقِيَٰمَةِ يُخْزِيهِمْ وَيَقُولُ أَيْنَ شُرَكَآءِىَ ٱلَّذِينَ كُنتُمْ تُشَٰٓقُّونَ فِيهِمْ ۚ قَالَ ٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ إِنَّ ٱلْخِزْىَ ٱلْيَوْمَ وَٱلسُّوٓءَ عَلَى ٱلْكَٰفِرِينَ

Sahih al-Bukhari
Laws of Inheritance (Al-Faraa'id)
Chapter: “Whoever leaves some property, then it is for his family.”
Narrated Abu Huraira:
The Prophet (ﷺ) said, "I am more closer to the believers than their own selves, so whoever (of them) dies while being in debt and leaves nothing for its repayment, then we are to pay his debts on his behalf and whoever (among the believers) dies leaving some property, then that property is for his heirs."
