The true friend, helper, guardian, and protector of believers is Allah. He knows everything and has power over everything. In addition, He eases the believers' burdens and makes them strong and superior. This is why believers never succumb to hopelessness, despair, sorrow, carelessness, or surrender.
Allah promises in the following verse that He will help those who follow His path:
Those who were expelled from their homes without any right, merely for saying: "Our Lord is Allah." If Allah had not driven some people back by means of others, monasteries, churches, synagogues, and mosques, in which Allah's name is mentioned much, would have been pulled down and destroyed. Allah will certainly help those who help Him – Allah is All-Strong, Almighty. (Surat Al-Hajj: 40)
Allah also conveys the following good news: Irrespective of the indestructible appearance of the unbelievers' rule and conspiracies, their efforts will come to naught and they will not achieve the results they desire. Every conspiracy and scheme to disseminate evil and immorality will eventually fail, and the schemes of those who organize evil and immorality will turn against them, for Allah states:
They concocted their plots, but their plots were with Allah, even if they were such as to make the mountains vanish. Do not imagine that Allah will break His promise to His Messengers. Allah is Almighty, Exactor of punishment. (Surah Abraham: 46-47)
It only increased their aversion, shown by their arrogance in the land and evil plotting. But evil plotting envelops only those who do it. Do they expect anything but the pattern of previous peoples? You will not find any changing in the pattern of Allah. You will not find any alteration in the pattern of Allah. (Surah Fatir: 42-43)
The duty of all believers is clear, whether they are Muslims, Jews, or Christians: to unite and join forces in order to establish societies dominated by peace, tranquility, prosperity, morality, goodness, happiness, and security. If we coordinate our efforts for such a pure undertaking, Allah will give us success. Every believing Christian, Muslim, and Jew is responsible to do whatever he or she can in this respect. Given that they believe in the One and Only Allah, try to win His good pleasure, have submitted to Him wholeheartedly, praise Him, and advocate essentially the same values, it is only natural for them to join together to fight their common foe.
Jews, Christians, and Muslims must permanently end all of their historical disputes, prejudices, misunderstandings, and conflicts caused by bigotry and bias. They must not forget that we have not even one day to waste. Followers of all three divinely revealed religions should approach each other with understanding and love, for what matters most is to point out their common ground and make things easier for everyone, to be constructive and complimentary, and to unite.
Say: "O People of the Book! Come to a proposition that is the same for us and you – that we should worship none but Allah (God), not associate any partners with Him, and not take one another as lords besides Allah." If they turn away, say: "Bear witness that we are Muslims." (Surah Al 'Imran: 64)
The prejudices caused by ignorance or by the agitation of those who oppose the morality of religion must be eradicated. All of the walls that have been erected over the years among and against the followers of Islam, Christianity, and Judaism only help the unbelievers undermine and lead people further away from religious morality. In this book, we have called upon the People of the Book: Let us join forces in the ideological fight against all ideologies that promote immorality and irreligion, especially Darwinism. Let us pool our technological resources and knowledge, our experience and efforts. Let us announce the errors of the followers of Darwinism, evolutionism, and materialism in the light of current scientific research. Let us move together to tell all people that Almighty Allah created the universe and all things therein, whether alive or lifeless, along with all of the supporting evidence and its miracles.
No doubt, those who call to goodness, recommend doing good and avoiding evil, and work together in this holy cause can expect salvation and eternal happiness. The unbelievers will be at a loss, whereas the believers will receive an eternal reward:
By the Late Afternoon, truly man is in loss – except for those who believe and do right actions and urge each other to the truth and urge each other to steadfastness. (Surat Al-'Asr: 1-3)
