How is the inheritance divided between the wife and the daughter, and what is the share of each of them if the husband dies?

If a woman dies leaving behind only a husband and a daughter, with no other heirs, then her husband receives one-fourth as his obligatory share due to the presence of a lineal descendant. Her daughter receives one-half as her obligatory share. The remainder is returned to the daughter and not to the husband. Thus, the inheritance is divided into four shares: one share for the husband as his obligatory portion, and three shares for the daughter (two shares as her obligatory portion and one share as ردّ [return/residue]).
