And anyone among you who does so on purpose should offer livestock of equivalent value , determined by two honourable persons among you , ( as atonement ) , to be brought to the Ka 'bah as an offering ; or else expiate by giving food to the poor , or its equivalent in fasting , so that he may realise the gravity of his deed . God has forgiven what has happened in the past ; but any one who does so again will be punished by God .
