Does the second wife inherit?

The questioner did not state their question; what they mentioned was merely information without a question following it. If they are asking about the method of inheritance distribution, then clarification can only be provided after an accurate and unambiguous enumeration of the heirs.

As an illustrative example, if it is assumed that the deceased left no heirs except for his wife, son, and daughter, then his wife receives one-eighth due to the presence of a lineal descendant, based on the Almighty's saying: ﴿But if you have a child, then for them is one-eighth of what you leave, after any bequest you [may have] made or debt.﴾ [An-Nisa:12]. The remainder goes to the son and daughter by way of ta'sib (residuary heirship), with the male receiving the share of two females, based on the Almighty's saying: ﴿Allah instructs you concerning your children: for the male, what is equal to the share of two females.﴾ [An-Nisa:11].

In this case, the inheritance is divided into twenty-four shares: the deceased's wife receives three shares (one-eighth), the son fourteen shares, and the daughter seven shares.
