Narrated Abu Huraira:

The Prophet ﷺ said, "There is no believer but I, of all the people, I am the closest to him both in this world and in the Hereafter. Recite if you wish: 'The Prophet is closer to the believers than their own selves.' (33.6) so if a believer (dies) leaves some property then his relatives will inherit that property;
but if he is in debt or he leaves poor children, let those (creditors and children) come to me (that I may pay the debt and provide for the children), for them I am his sponsor (surely).

حَدَّثَنِي إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، حَدَّثَنَا مُحَمَّدُ بْنُ فُلَيْحٍ، حَدَّثَنَا أَبِي، عَنْ هِلاَلِ بْنِ عَلِيٍّ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَمْرَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ ﷺ قَالَ " مَا مِنْ مُؤْمِنٍ إِلاَّ وَأَنَا أَوْلَى النَّاسِ بِهِ فِي الدُّنْيَا وَالآخِرَةِ، اقْرَءُوا إِنْ شِئْتُمْ النَّبِيُّ أَوْلَى بِالْمُؤْمِنِينَ مِنْ أَنْفُسِهِمْ فَأَيُّمَا مُؤْمِنٍ تَرَكَ مَالاً فَلْيَرِثْهُ عَصَبَتُهُ مَنْ كَانُوا، فَإِنْ تَرَكَ دَيْنًا أَوْ ضِيَاعًا فَلْيَأْتِنِي وَأَنَا مَوْلاَهُ ".
