Sahih Muslim
The Book Pertaining to the Rules of Inheritance (Kitab Al-Faraid)
Book Number: 011 / Hadith Number: 3946
Abn Huraira (Allah be pleased with him) reported Allah's Apostle (may peace be upon him) having said this: 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.
