A woman came to the Messenger of Allah ﷺ and said: My mother has died, and fasts of a month are due from her. Thereupon he said: Don't you see that if debt was due from her, would you not pay it? She said: Yes (I would pay on her behalf). Thereupon he said: The debt of Allah deserves its payment more than (the payment of anyone else). (Using translation from Muslim 1148a)
جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ إِنَّ أُمِّي مَاتَتْ وَعَلَيْهَا صَوْمُ شَهْرٍ أَفَأَصُومُ عَنْهَا؟ فَقَالَ «أَرَأَيْتَ لَوْ كَانَ عَلَيْهَا دَيْنٌ أَكُنْتَ تَقْضِيهِ؟» قَالَ نَعَمْ قَالَ «فَدَيْنُ اللهِ أَحَقُّ أَنْ يُقْضَى»
