You observe prayer for your companion. But when Allah opened the gateways of victory for him, he said: I am nearer to the believers than themselves, so if anyone dies leaving a debt, its payment is my responsibility, and if anyone leaves a property, it goes to his heirs.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُؤْتَى بِالرَّجُلِ الْمَيِّتِ عَلَيْهِ الدَّيْنُ فَيَسْأَلُ هَلْ تَرَكَ لِدَيْنِهِ مِنْ قَضَاءٍ فَإِنْ حُدِّثَ أَنَّهُ تَرَكَ وَفَاءً صَلَّى عَلَيْهِ وَإِلاَّ قَالَ صَلُّوا عَلَى صَاحِبِكُمْ فَلَمَّا فَتَحَ اللَّهُ عَلَيْهِ الْفُتُوحَ قَالَ أَنَا أَوْلَى بِالْمُؤْمِنِينَ مِنْ أَنْفُسِهِمْ فَمَنْ تُوُفِّيَ وَعَلَيْهِ دَيْنٌ فَعَلَىَّ قَضَاؤُهُ وَمَنْ تَرَكَ مَالاً فَهُوَ لِوَرَثَتِهِ  

This hadith has been narrated on the authority of al-Zuhri through another chain of transmitters.  

عَنِ الزُّهْرِيِّ بِهَذَا الإِسْنَادِ هَذَا الْحَدِيثَ  

By Him in Whose Hand is the life of Muhammad, there is no believer on the earth with whom I am not the nearest among all the people. He who amongst you (dies) and leaves a debt, I am there to pay it, and he who amongst you (dies) leaving behind children I am there to look after them. And he who amongst You leaves behind property, that is for the inheritor whoever he is.  

عَنِ النَّبِيِّ ﷺ قَالَ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ إِنْ عَلَى الأَرْضِ مِنْ مُؤْمِنٍ إِلاَّ أَنَا أَوْلَى النَّاسِ بِهِ فَأَيُّكُمْ مَا تَرَكَ دَيْنًا أَوْ ضَيَاعًا فَأَنَا مَوْلاَهُ وَأَيُّكُمْ تَرَكَ مَالاً فَإِلَى الْعَصَبَةِ مَنْ كَانَ  

This is what Abu Huraira (Allah be pleased with him) narrated to us from Messenger of Allah (may peace he upon him). And he narrated many ahadith, and one was this: Messenger of Allah (may peace be upon him said: I am, according to the Book of Allah, the Exalted and Majestic, nearest to the believers of all the human beings. So whoever amongst you dies in debt or leaves behind destitute children, you should call me (for help) ), for I am his guardian. And who amongst you leaves property, his inheritor is entitled to get it, whoever he is.  

عَنْ رَسُولِ اللَّهِ ﷺ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ ﷺ أَنَا أَوْلَى النَّاسِ بِالْمُؤْمِنِينَ فِي كِتَابِ اللَّهِ ﷻ فَأَيُّكُمْ مَا تَرَكَ دَيْنًا أَوْ ضَيْعَةً فَادْعُونِي فَأَنَا وَلِيُّهُ وَأَيُّكُمْ مَا تَرَكَ مَالاً فَلْيُؤْثَرْ بِمَالِهِ عَصَبَتُهُ مَنْ كَانَ  

He who leaves property, that is for the inheritors; and he who leaves behind destitute children, then it is my responsibility (to look after them).  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ مَنْ تَرَكَ مَالاً فَلِلْوَرَثَةِ وَمَنْ تَرَكَ كَلاًّ فَإِلَيْنَا  

This hadith has been narrated on the authority of Shu'ba with the same chain of transmitters.  

أَنَّ فِي حَدِيثِ غُنْدَرٍ وَمَنْ تَرَكَ كَلاًّ وَلِيتُهُ
