This book is based on the Saudi Arabian Curriculum which is taught in all the primary schools in the KSA. It covers the full series of authentic Islamic knowledge through the primary school ages. It is important for all kids to have knowledge of these matters. Tawheed (التوحيد) - is to single out Allaah in all types of worship. So whatever is considered to be worship, which is to do an act which is pleasing to Allaah in order to get closer to Allaah and follow the path that Allaah has commanded His slaves to follow. So the Muslim does every action in order to please his Creator, his Sustainer, and his Owner who is Allaah alone. This is the intention of doing all good deeds. Tawheed is of three different types First is the Tawheed of Lordship this in Arabic is called Al-Ruboobiyya which comes from the word Rabb (Lord). Our Lord, Allaah the Most High is Our Creator, Our Sustainer, Our Provider, and Our Owner.The second type of Tawheed is the Tawheed of worship. This means that once we have recognized and come to know that Allaah is our Lord. Then this means that we should also know that only Allaah has the right to be worshipped in truth. And no one other than Allaah deserves to be worshipped since only Allaah alone is our true Lord. So, therefore, the Tawheed of Worship is called in Arabic Tawheed Al-Uloohiyya. The third type of Tawheed is the Tawheed of the names and attributes of Allaah the Most High. In Arabic it is called Tawheed "Al-Asma-was-Sifaat"
