The Book Pertaining to the Rules of Inheritance (Kitab Al-Farai`d)
Muslim :: Book 11 : Hadith 3948
Abu Huraira (Allah be pleased with him) reported Allah's Apostle (may peace be upon him) as saying: 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). This hadith has been narrated on the authority of Shu'ba with the same chain of transmitters.
