How is the deceased's estate, amounting to 7 feddans, to be divided among his heirs: (one son, 7 daughters, and one wife), after settling his debts of 300,0?

If the heirs are limited to the wife, the son, and the daughters, the wife receives one-eighth due to the existence of a direct descendant. The remainder is for the son and daughters by way of ta’sib (agnatic inheritance), with the male receiving the equivalent of the share of two females. The estate, after settling debts, is divided into 72 shares: the wife receives 9 shares, each daughter receives 7 shares, and the son receives 14 shares. The matter should be referred to the Sharia courts to verify the absence of other heirs, wills, or debts.
