Allah ﷻ mengutus para Rasul-Nya, menurunkan Wahyu-Nya, dan menciptakan langit dan bumi agar disembah, hanya Dia semata. Allah ﷻ menghendaki agar segala ketaatan dan seruan ibadah diarahkan kepada-Nya ﷻ, kerana Dia ﷻ adalah Tuhan Yang Esa, yang memiliki segala sesuatu. Allah ﷻ telah berfirman: (Aku (Allah) tidak menciptakan jin dan manusia melainkan supaya mereka menyembah-Ku (semata-mata)).1 (Kami tidak menciptakan langit dan bumi serta segala yang ada di antara keduanya melainkan dengan kebenaran).2 (Allah-lah yang menciptakan tujuh langit dan dari bumi seperti itu juga. Perintah-Nya turun di antara langit-langit dan bumi itu, supaya kamu mengetahui bahawa Allah Maha Kuasa atas segala sesuatu, dan bahawa Allah meliputi segala sesuatu dengan ilmu-Nya.)3 (Allah telah menjadikan Ka'bah, Rumah Suci itu, sebagai tempat yang aman dan manfaat bagi manusia, begitu juga bulan Haram, binatang-binatang hadyu dan binatang-binatang qalaid, yang demikian itu supaya kamu mengetahui bahawa Allah mengetahui apa yang ada di langit dan apa yang ada di bumi, dan bahawa Allah Maha Mengetahui segala sesuatu.)4 Maka Allah ﷻ telah memberitahu kita bahawa tujuan penciptaan dan perintah-Nya ialah agar Dia dikenali melalui Nama-Nama dan Sifat-Sifat-Nya, dan agar Dia, hanya Dia, disembah tanpa menyekutukan sesuatu pun dengan-Nya. Dia ﷻ menghendaki manusia berlaku adil sesama mereka, kerana keadilan inilah yang menjadi asas bagi tegaknya langit dan bumi; Dia ﷻ berfirman: (Sesungguhnya Kami telah mengutus Rasul-Rasul Kami dengan membawa bukti-bukti yang nyata, dan telah Kami turunkan bersama mereka Kitab dan neraca (keadilan) agar manusia dapat melaksanakan keadilan).5 Contoh keadilan yang tertinggi ialah tauhid (menyembah Allah semata-mata), manakala kezaliman yang paling besar ialah syirik, iaitu dosa besar yang paling besar. Seseorang hendaklah merenungkan asas ini dengan baik, dan mengetahui perinciannya, supaya dia dapat mempelajari hikmah Hakim Yang Terbaik (Allah ﷻ) dalam setiap perkara yang Dia perintahkan untuk dilakukan serta setiap perkara yang Dia larang. Dasar Syirik (politeisme) tentulah bertentangan dengan Tauhid (monoteisme), oleh itu Syirik ditakrifkan sebagai dosa besar yang paling berat. Akibatnya, Allah ~ telah mengharamkan setiap orang musyrik daripada memasuki Syurga. Dia ~ telah menghalalkan, bagi orang Islam, darah, harta dan keluarga seorang musyrik, dan mereka bahkan boleh dijadikan hamba. Hal ini kerana mereka telah menolak Perintah Allah ~ untuk beribadah kepada-Nya sahaja. Dia ~ tidak menerima sebarang amalan orang musyrik, dan Dia juga tidak menerima sebarang syafaat daripada mereka. Dia ~ tidak akan memperkenankan doa mereka di Akhirat, kerana mereka adalah golongan yang paling jahil tentang-Nya ~, lantaran mereka menyekutukan-Nya dengan sekutu, yang merupakan perbuatan zalim yang paling buruk daripada pihak mereka, walaupun sebenarnya mereka hanya berlaku zalim terhadap diri sendiri.

Allah ~ sent His Messengers, sent down His Revelation, and created the heavens and the earth in order to be worshipped, Alone. Allah ~ wants all obedience and invitations of worship to be directed to Hirn ~. as He ~ is the One God, Who owns all things. Allah ~ has said: (I (Allah) did not create the jinn and mankind except that they should worship Me (Alone)) 1 (We did not create the heavens and the earth and all that is between them except with the truth)2 (It is Allah Who has created seven heavens and of the earth the like thereof. His Command descends between them, that you may know that Allah has power over all things, and that Allah surrounds all things in (His) Knowledge.) 3 ( Allah has made the Ka'bah, the Sacred House, an asylum of security and benefits for mankind, and also the Sacred Month and the animals of offerings and the garlanded, that you may know that Allah has knowledge of all that is in the heavens and that is in the earth; and Allah is the All-Knower of all things.)4 So Allah ~ has informed us that the purpose of His Creation and Command is: that He should be known through His Names and Attributes, and that He, Alone, should be worshipped, without associating any partner with Him. He ~ wants people to act fairly among themselves, as this fairness is the justice upon which the heavens and the earth were established; He ~ said: (Indeed, We have sent Our Messengers with clear proofs, and revealed with them the Scripture and the Balance Gustice) that mankind may keep up justice) 5 The highest example of justice is Monotheism (Worshipping Allah, Alone), while the greatest act of injustice is polytheism, being the greatest of the major sms. One should reflect well on this foundation, and know its details , in order to learn the wisdom of the Best of Judges (Allah ~ ), in everything that He has Commanded to do as well as everything He forbade. The basis of Shirk (polytheism) is certainly the opposite of Tawhid (Monotheism), and therefore Shirk is defined as the greatest of the major sins. Consequently, Allah ~ has forbidden the entry of every polytheist to Paradise. He ~ has legalised, for the Muslims, the blood, property and family of a polytheist, and they may even be taken as slaves. This is because they have rejected the Command of Allah ~ to worship Him, Alone. He ~ does not accept any of the deeds of polytheists, nor does He accept any intercession from them. He ~ will not answer their supplications in the Hereafter, because they were the most ignorant of Him ~' as they associated partners with Him, which was the worst act of injustice on their part, even though they were simply acting unjustly towards themselves.
