A man came to the Prophet ﷺ and said to him, "My sister vowed to perform the Hajj, but she died (before fulfilling it)." The Prophet ﷺ said, "Would you not have paid her debts if she had any?" The man said, "Yes." The Prophet ﷺ said, "So pay Allah's Rights, as He is more entitled to receive His rights."
أَتَى رَجُلٌ النَّبِيَّ ﷺ فَقَالَ لَهُ إِنَّ أُخْتِي نَذَرَتْ أَنْ تَحُجَّ وَإِنَّهَا مَاتَتْ فَقَالَ النَّبِيُّ ﷺ لَوْ كَانَ عَلَيْهَا دَيْنٌ أَكُنْتَ قَاضِيَهُ قَالَ نَعَمْ قَالَ فَاقْضِ اللَّهَ فَهْوَ أَحَقُّ بِالْقَضَاءِ
