Sahih Bukhari | Volume 6 | Hadith Number 304
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).
