How is the inheritance of the deceased divided, consisting of: (a son - a grandson - a full brother - a nephew - two daughters - a wife - a half-sister from the father's side), and what should the questioner do who took money from her deceased grandfather without his knowledge, and has regretted it and wants to repent, and how can the value of the taken money be estimated?

The wife's share is one-eighth due to the presence of a lineal descendant of the deceased who inherits. The remainder goes to the son and the two daughters by ta'sib (residuary inheritance), with the male receiving the equivalent of the share of two females. The other relatives mentioned do not inherit as they are excluded by the son. Taking money from the grandfather without his permission is a forbidden theft and a sin, and restitution for what was taken from him is obligatory, whether it was before or after reaching puberty. However, the sin of theft is incurred only after reaching puberty. The money must be returned to the grandfather's rightful heirs. If the exact amount is not known, you must be cautious and pay what you believe will most likely clear your conscience. Performing Umrah (definition) on behalf of the grandfather is a good deed, and its reward will reach him, but it does not absolve financial debts, which must be returned to their rightful owners or their forgiveness sought.
