What is the share of each heir from the estate of a sister who died without leaving a will, and who is survived by: a mother, a father, a husband, and 3 daughters?

The money your sister deposited with you is considered an inheritance to be divided among her heirs. If your sister left no one other than those mentioned, then her mother receives one-sixth, and her father receives one-sixth, due to the presence of a lineal descendant. Allah, the Almighty, says: "And for his parents, to each one of them a sixth of what he left if he had a child." Her husband receives one-fourth due to the presence of a lineal descendant. Allah, the Almighty, says: "But if they have a child, then for you is a fourth of what they leave after any bequest they [may have] made or debt." Her three daughters receive two-thirds, based on the saying of Allah, the Almighty: "But if there are [only] daughters, two or more, for them is two-thirds of what he left." This is a 'a'ilah (over-allotted) case, so the inheritance is divided into forty-five shares: her mother receives six shares, her father receives six shares, her husband receives nine shares, and each daughter receives eight shares.
