Inheritance classes under Muslim law determine sharers' fixed shares, residuaries' entitlement to residue, and distant kindred succession. Muslim law divides heirs into Sharers who receive prescribed fractional shares, Residuaries who take the residue after sharers' claims are met, and Distant Kindred who inherit only if there are no sharers or residuaries. Distribution occurs after funeral expenses, debts and legacies; sharers' shares are ascertained and allotted first, residuaries succeed to any remaining estate in a specified order, and distant kindred inherit only in the absence of both sharers and residuaries, with a special rule where a sole spousal sharer takes the spousal share and the remainder goes to distant kindred.
