humankind are able to reform
Muslims believe that all members of humankind are able to reform; in addition they believe that the possibility of successful reform is greater than the probability of failure. This belief is derived from the fact that God has given humankind the means to reform, not once but over and over again right up until close to the Day of Judgement. God sent Messengers and Prophets to each and every nation. Some we know from the Quran and the traditions of Prophet Muhammad, others are known only to God.
“And for every community or nation there is a Messenger; when their Messenger comes, the matter will be judged between them with justice, and they will not be wronged.” (Quran 10:47)
God does not hold any person responsible until he has been clearly shown the right way.
“…And We never punish until We have sent a Messenger. ” (Quran 17:15)
At the same time we are responsible to search for the truth and upon finding it we should accept it and reform our lives accordingly. The past bad actions can be left behind. There is no sin that cannot be forgiven!
“Say, ‘O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of God. Indeed, God forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.’” (Quran 39:53)
A person should take advantage of God’s mercy by sincerely repenting for the past or if one is not a believer, by converting to the religion of Islam. Every person must work towards his salvation by combining faith, belief and action.
