A very useful article shows the pure Islamic belief of monotheism. It briefly mentions that Allah alone is worthy of worship, He is worshipped directly and Allah is not like his creation nor his creation is like him.

Most people agree to the fact that Allah’s (God’s) Word cannot be contradictory. What He spoke about Himself must be true. He made Himself known as The Creator, The One, The Originator, and The Provider. He is the First, nothing is before Him; The Last, nothing is after Him; The Most High, nothing is above Him; The Most Near, nothing is beyond His reach, and He encompasses everything while He is above heavens, distinct and separate from His creatures. Great in His Majesty and Honor, Most Merciful, Severe in Punishment, All-Knower, Most Compassionate, All-Wise, and All-Just; Most Perfect in all of His Names and Attributes. He does not beget, nor is He begotten. There is no equal to Him, and there is nothing like unto him, and thus He alone deserves to be worshipped. In essence, the religion as revealed1 to nations before us and to mankind up to the Day of Resurrection, calls for the worship of none but God (Allah).

A book which explains the Prohibitions That Are Taken Too Lightly, Allah has laid down obligations which we are not permitted to ignore, and has set limits which we are not permitted to transgress, and has set out prohibitions which we are not allowed to violate.

Bulugh Al-Maram (attainment of the objective according to the evidence of the ordinances) is based upon the Ahadith of our Prophet which have been the sources of Islamic Jurisprudence. Al-Hafiz Ibn Hajar Al-Asqalani has recorded the true significance of the Ahadith and their origins & also made a comparison of the versions, if the sources are more than one.

Introduction to history of polytheism and monotheism: Allah (glory be to him) created all people as Muslims and monotheists but devils came to them and changed and distorted their religion. Allah said in a qudsi hadith, “I created all my slaves as haneefs (monotheists), but the devils came to them, made them deviate from their religion, forbade them that which I had permitted to them, and commanded them to join partners with me for which I has given no authority.” As soon as people commit a type of polytheism, Allah sends his prophets to call them to the suitable type of monotheism.
