Division of the estate of a man who died and left behind a wife, mother, brother and sister
Question

                A man died leaving behind a wife, a brother, a sister and a mother. How will the estate be shared among this heirs?
Praise be to Allah.The 
          man's estate should be divided among the heirs mentioned in the following 
          manner:   
The 
          wife is given a quarter, the mother is given one-sixth, and the rest 
          is shared between the brother and sister giving the male twice the share 
          of the female.   
So 
          if, for example, he left behind 18,000:   
His 
          wife gets one quarter of the estate, which is 4500.   
His 
          mother gets one-sixth of the estate, which is 3000.   
The 
          rest (18,000 – 7500= 10,500) is divided into three shares.   
One 
          third is given to the female, 3500.   
Two-thirds 
          are given to the male, 7000.   
And 
          Allaah knows best.
