Muwatta Imam Malik (Riwayat Yahya)

Imam Malik, may Allah have mercy on him, said that when the deceased has neither a son nor a daughter nor a grandson nor a granddaughter, then the husband will receive half of the estate. If the deceased has children or the children of the deceased’s son, whether male or female, then the husband will receive one-fourth share after fulfilling the will and debt. And when the husband dies and there are no children nor children of his son, then his wife will receive one-fourth share. If there are children or children of the son, whether male or female, then the wife will receive one-eighth share after fulfilling the will and debt, because Allah, Glorious and Exalted is He, says: “For you is half of what your wives leave if they have no child, but if they have a child, then for you is one-fourth of what they leave after any bequest they may have made or debt. And for the women is one-fourth of what you leave if you have no child, but if you have a child, then for them is one-eighth of what you leave after any bequest you may have made or debt.”
