Sahih Bukhari Volume 6, Book 65, Hadith 4783

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 صلى الله عليه وسلم 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 ‏"

Narrated By Abu Huraira : The Prophet 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).
