A Da`y (caller to Islam/Allah) should invite people to clarify one thing as done by all messengers (peace be upon them) that is, Allah's straight path, which is Islam, the true religion of Allah. In fact, this should be the objective of Da`wah (calling to Islam).
Invite (mankind, O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴـﻪ ﻭ ﺳـﻠﻢ) to the Way of your Lord (i.e. Islâm)
The way of Allah is Islam, the straight path. It is Allah's religion with which He sent His Prophet Muhammad (peace be upon him). It is the principle to which people should be called, not the ideology or thought of any one. People should be called to Allah's straight path with which He sent His Prophet Muhammad (peace be upon him) and which is indicated by the Qur'an and authentically narrated Sunnah of the Prophet (peace be upon him). The starting point thereof should be calling people to the sound `Aqidah (creed), devotedness to Allah, worshiping Him alone and believing in Him, His messengers, the Last Day and all that Allah and His Messenger told us. This is the essence of the straight path, namely, calling people to admitting Allah's Oneness, being devoted to Him and believing in Him and His messengers (peace be upon them). To this may also be added calling people to believing in all that we were told about by Allah and His Messenger, regarding past events, the Hereafter, the end of time and others. And calling people to Allah's obligations, such as performing Salah (Prayer), paying Zakah (obligatory charity), fasting Ramadan, Hajj and the like; inviting people to Jihad in the Cause of Allah, enjoining what is good, forbidding what is evil and abiding by Allah's commandments regarding Taharah (ritual purification), Salah, transactions, marriage, divorce, crimes,
expenditure, war, peace and all other affairs. This is because Allah's religion is of a comprehensive nature in that it deals with people's interests in this world as well as in the Hereafter and all that people need in religion. It also calls to proper conduct and good deeds and forbids immorality and bad deeds. It comprises worship and leadership, in the sense that a Muslim may be a worshiper and an army commander. It also comprises worship and rule, in the sense that a Muslim may be a worshiper who offers Salah (Prayer) and observes Sawm (Fast) and a ruler who puts Allah's laws and rulings into practice. It also comprises worship and Jihad, in the sense that a Muslim calls people to Allah and fights in Allah's Cause against those who forsake Allah's religion that is, Qur'an and sword, in the sense that a Muslim contemplates and reflects on the Qur'an and puts its rulings into practice even by the force of sword if it is necessary. It also comprises politics and sociality, in the sense that it propagates good conduct, brotherhood and unity of Muslims.
And hold fast, all of you together, to the Rope of Allâh (i.e. this Qur'ân), and be not divided among yourselves
Thus, Allah's religion calls people to a sagacious, sound polity that unites not separates, brings hearts closer not sows division, respects Islamic brotherhood, calls for cooperation with one another in good and piety, advises people for the sake of Allah, urges people to render back trusts, enforces Shari`ah (Islamic law), and abandons judgment with which Allah has not enacted.
Verily, Allâh commands that you should render back the trusts to those to whom they are due; and that when you judge between men, you judge with justice.
This religion is also politics and economics, policy, worship and jihad. It adopts a balanced economic system that is in a medium position between extremist ideologies. It is not cruel, unjust capitalism that does not know religious limits and admits acquisition of money by hook or by crook. It is not an atheistic communistic system that does not respect private ownership, and does not hesitate to commit injustice, atrocities and aggression against people. Rather, it is between the two extremes and follows a middle course between both false systems. Westerners highly esteemed and loved money so much
and accumulated it by all possible means even if prohibited by Allah (Glorified and Exalted be He). However, Eastern atheist Soviet Russians and those who followed their system did not respect private ownership and confiscated people's properties forcibly, feeling no shame. On the contrary, they enslaved and prosecuted people, disbelieved in Allah, denied all religions, and said life is materialistic. Therefore, they felt unmistaken to overtake unrightfully the properties of people. They also did not feel any pricking of conscience for committing genocide and taking over wealth. They did not consider worthwhile the means of lawful earning that Allah has sanctioned, i.e. acquiring money through exploiting one's physical and mental abilities as well as all other tools granted to one by Allah. On the other hand, Islam's economic system protects private property, provides for acquisition of money by lawful means and prohibits unlawful means or acquiring money by injustice, cheating, usury and oppression. Rather, it respects and recognizes the inviolability of individual and public ownership. Islam is thus in a medium position between the two unjust economic systems, in that it declares that acquisition of money is lawful and encourages people to acquire it but in a judicious way, which may not hinder a person from his obligations to Allah and His Prophet (peace be upon him).
O you who believe! Eat not up your property among yourselves unjustly
The Muslim is inviolable for his Muslim brother, as for his blood, wealth and honor.
Your blood, your properties and your honors are as sacred to one another as the sanctity of this day of yours in this month of yours in this town of yours.
It is better for anyone of you to take a rope (and cut) and bring a bundle of wood (from the forest) over his back and sell it and Allah will save his face (from the HellFire) because of that, rather than to ask the people who may give him or not.
