Ref. No. 1860/43-1715
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
In father’s property after his death, the son gets double share and daughter gets single share. So, if the legal heirs are only one son and four daughters, then the entire property left by father shall be divided into six shares, out of which two shares shall go to the son, and each daughter will get one share.
لقوله تعالى: يُوصِيكُمُ اللّهُ فِي أَوْلاَدِكُمْ لِلذَّكَرِ مِثْلُ حَظِّ الأُنثَيَيْنِ . [النساء : 11
