All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
If the deceased left behind a wife, three daughters, and four sons and did not leave any other heir, then his wife gets one eighth as her legal share due to the existence of the children (direct heirs); Allah says (what means): {But if you leave a child, then for them [i.e. the wives] is an eighth of what you leave, after any bequest you [may have] made or debt.} [Quran 4:12]
The remainder should be divided amongst the sons and daughters by Ta’seeb (by virtue of having a paternal relation with the deceased and not having an allotted share, so they get what is left after the allotted shares have been distributed); the male twice the share of the female, as Allah says (what means): {Allah instructs you concerning your children [i.e. their portions of inheritance]: for the male, what is equal to the share of two females.}[Quran 4:11]
Therefore, the inheritance should be divided into 88 shares, the wife gets one eighth, which is 11 shares; each son gets 14 shares; and each daughter gets 7 shares.
It is not clear to us what you mean by saying: "…our father distributed the property according to the Shariah concern, and that time all our sisters told us that they were not asking for their parts…"; do you mean that he distributed it to you in his lifetime while he was in good health, in which case it is a gift? Or do you mean that he ordered that it be divided amongst you after he dies, as may be understood from the statement of the daughters, who said that "they were not asking for their parts…" Likewise, the rest of what you mentioned is somewhat ambiguous and needs a clarification of some details, so we cannot answer it. Hence, we advise you to orally ask the scholars about it.
Allah knows best.
