(Fatwa: 286/275/SD=4/1439)
In the above mentioned case, if your deceased mother left only two sons, two daughters and her husband (your father) who are alive and none is alive among her parents then the property of the mother shall be divided into eight (8) shares, after paying due rights proceeding inheritance. Out of the total, her husband shall get 2 shares, 2-2 shares shall go to each son, while each daughter shall get 1-1 share. If your mother gave some jewelry to your elder sister into her complete possession then she shall remain its sole owner and no division shall be made in it. If the case is different, explain it and submit the question again.
Allah knows Best!
