It is sometimes translated, 'the practice of charity,' but that is inexact. Every act of kindness is regarded as done out of one's love for his fellow beings. [V. Abrahams, I., C.P.B. p. XIII. The inner meaning of the phrase is, 'making good.' 'requiting' — a making good to man for goodness of God, and it is connected with tenderness and mercy to all men and all classes; cf. J.

A. A dowry gift becomes the property of the donee only if the marriage takes place. Therefore, neither A nor his daughter has ever gained title to B's money, and A must return the principal plus the interest to B. Even if B expressly stipulated that he will forfeit the 15 pounds if the marriage does not take place, such a stipulation is considered an Asmakhta and is not valid. B, however, must pay A for his trouble in managing B's investments.
