Human perceptions and faiths are based on information. If information is correct, perception is also correct and if information is wrong, perception is also wrong. For example, centuries ago it was believed that our earth is flat and stationary, but later on increase in the knowledge proved it to be wrong.
human mind can be programmed and re programmed. Wrong concept and ideas can be replaced by correct concept and ideas with availability of correct information. False perception can be replaced by true perception. Only thing is that man should be ready for updating his mind with correct information. If a person is not willing for change and updating his mind, no amount of evidence can correct his faulty concepts.
Many people believe in existence of One Almighty God. But different people have different concept of God which is a cause of conflict and confusion in the human society. Who can give us the correct concept of God? Indeed, Almighty God Himself can give us correct concept of God. Otherwise people are totally in dark about God and in efforts to know about God themselves, they develop lot of concept and ideas which are contradictory and confusing and does not befit God and is a source of conflict in the society.
But Almighty God does not want man to remain ignorant about God. Almighty God does not want man to develop wrong and faulty ideas about God, which is a source of permanent division in the society. In fact, Almighty God wants people to be united and leave peacefully. And it is possible if mankind is provided with correct information about God by God Himself. It is possible only if wrong perception about God is replaced by true perception of God.
Therefore, man needs guidance from Almighty God. Therefore, from day one Almighty God made a system of informing and guiding man through His messengers and prophets from among man chosen by Him and sending scriptures with them.
“Mankind was once a single community, (but people developed differences), then God sent prophets to them as bearers of good tidings and warning, and sent down with them the Scripture containing the truth, so that He might judge between their disputes. And none differed over it (the Scripture) except those who were given it, after clear signs had come to them, out of jealous animosity among themselves. Then, God by His will guided the believers to the truth about which the others had disputed. And God guides whom He will to a straight path.” (Al Quran 2: 213)
“Say (O Muhammed), ‘my Lord has forbidden indecencies, both open and hidden, and sin and wrongful oppression and that, you associate things with God, for which He has not sent down authority, and that you say things about God that you do not know. For all people a term has been appointed. And when their term approaches, they can neither delay it by a single moment, nor can they advance it. [Al Quran 7:33-34]
Truly your Lord is God who created the heavens and the earth in six periods, then He ascended the Throne, governing the whole affair. No one can intercede with Him except with His permission. Such is God, your Lord, so worship Him alone. Will you not take heed? (Al Quran 10: 3)
“Allah (God), there is no deity except Him. The Ever Living, the Self Existent. Neither slumber overtakes Him, nor sleep. To Him belongs whatever is in the Heavens and whatever is on the earth. Who can intercede with Him except by His permission? He knows all that is before them and all that is behind them. They can grasp only that part of His knowledge which He wills. His throne extends over the heavens and the earth. And He feels no fatigue in guarding them. And He is the Most High and Supreme. (Al Quran 2:255)
‘They have even dared to attribute sons and daughters to Him without knowledge. Glorified be He and High Exalted above what they attribute to Him. The Originator of the heavens and the earth. How can He have a son and when there is for Him no companion? And He created everything, and He is aware of everything.’ (Al Quran 6: 100)
‘The Kingdom of the Heavens and the earth and everything between them belong to God. He creates what He will and God has power over all things. (Al Quran 5:17)
“No vision can grasp Him, but He takes in over all vision. And He is the Most Subtle, the All Aware. (Al Quran 6: 103)
“Say, He is God, the One God, the self Sufficient One. He begets not, nor was He begotten. And there is no one like Him. (Al Quran 112: 1-4)
“All that is on the earth is doomed to perish, while your Lord’s own Self will remain full of majesty and glory. So, which of your Lord’s wonders would you deny?” [Al Quran 55: 26-28]
Although man is given intelligence to fulfil his basic requirement and comfort, man does not know what role he is supposed to play in this life. Man does not know what kind of life he is supposed to spend in this world. Man does not know why Almighty God has created mankind. Man does not know what is truth and what is falsehood. Man does not know what is going to happen to him after his death. Then, who can give correct information about it? Only God can give correct information about it. Therefore, man needs guidance from Almighty God. Therefore, Almighty God informed and guided mankind of all the previous nations and generations. And God has also informed us and guided. But, we should be ready to receive and accept His guidance, if we want peace in this life and in the Hereafter. If we are not ready for that, then we alone are responsible for our fate. Fate in this world and in the Hereafter.
Therefore, God has also informed man that his temporary life on the face of this earth is a trial. God wants to test the decision making capacity of man as He has made the human being the most intelligent specie on the face of this earth. God has given mankind power to rule on the land. He wants to test the conduct of man giving him freedom of thought, choice and action. This freedom and power is the foundation of trial.
“Blessed is He in Whose hand is the Kingdom and He has power over all things. He created death and life so that He might test you and find out which of you is best in conduct. And He is Almighty, All Forgiving. (Al Quran 67: 1-2)
Almighty God has given us freedom to choose the truth or falsehood as a part of test of human intelligence. Who followed truth and who followed falsehood cannot be decided unless and until God Himself deliver justice. Therefore, Almighty God has appointed a Day to deliver His Judgement on the decision of mankind to select a particular path, and to resolve all disputes which many people had created so that people who chose to follow truth are recompensed and those who chose to follow falsehood are also recompensed. And God has informed us about it also.
“Say (O Muhammed), O Mankind! Truth has come to you from your Lord. So anyone who accepts guidance is guided only for his own self, and he who goes astray does so at his own. And I am not a custodian over you. And follow that which is revealed to you, and remain patient until God gives judgment. And He is the best of judges.” (Al Quran 10: 108-109)
“And had God so willed, He would have made you a single community (nation), but in order to try you by what He has given you. So compete with one another in good deeds. To God you shall all return, then He will inform you about what you have been disputing.” (Al Quran 5: 48)
‘The Hour is surely coming. I choose to keep it hidden, so that every human being may be recompensed in accordance with his efforts.’ [Al Quran 20:15]
Then what is going to happen after death, Almighty God has also informed us about it.
“Ask (O Muhammed), to whom belongs all that is in the heavens and earth? Say, To God. He has decreed upon Himself mercy. He will surely assemble you on the Day of Resurrection, there is no doubt about which. Those who have lost their souls will not believe.” [Al Quran 6: 12]
“When the greatest disaster will strike. On that Day man will recall all that he had striven for. And Hell shall be placed in full view of all. Then he who had rebelled and preferred the life of this world shall have his abode in Hell. But he who had feared standing before his Lord and curbed his evil desires. Then he shall have his home in Paradise. They ask you (O Mohammed) about the Hour, when will it come? But it is not for you to tell about it. Only your Lord knows when it will come. You are but a warner to him who fears it. On that Day, when they shall see it, they shall feel as if they had stayed (in this world) only one evening or one morning.” (Al Quran 79: 34-46)
“The Day We shall make the mountains move and you will see the earth laid bare. And We shall gather all mankind together and shall not leave anyone of them behind. They will be ranged before your Lord, standing in rows and He will say to them, ‘Indeed, you have come to Us just as We created you the first time. But you supposed that We would not appoint the time for the fulfilment of Our promise to you.’ The Book (of deeds) will be placed before them and you will see the guilty apprehensive about its contents. They will say, ‘Woe to us! What a record this is! It does not leave any deed, small or large, unaccounted for! They will find everything they ever did laid open in front of them. Your Lord will not be unjust to anyone.” [Al Quran 18: 47-49]
“Man asks, ‘When I am once dead, shall I be raised to life? But does man not remember that We created him when he was nothing before?” [Al Quran 19:66]
“We give whatever We will to whoever desires immediate gains (in this world); but then We have prepared Hell for him which he will enter, disgraced and rejected. And anyone who desires the Hereafter and makes a proper effort to achieve it, being a true believer, then it is those whose efforts shall be appreciated.” [Al Quran 17: 18]
Therefore it is essential for man to know the true guidance of God in order to be successful in the Hereafter. Therefore, guidance from God is essential for man in order to achieve peace in this life and in Hereafter.
