On literal meaning, Tauhied means to unify. I mean to unify Allah The God. I mean that Allah is unifaid. Allah is the one in subtance/esence, character, and act. Allah is the one in subtance/esence We see the creatures around us that’s not single. We see the human and the human’s not single. If they aren’t here, they may be in the other place. There are a lot of plant also and there’re various of them. There are animals and they’re not single. We don’t see a single sun. The astronomer knows that there are the other suns yonder over there in the other galaxi, not the sun rising in the east and sitting in the west. But Allah, he is the one, the only one. There’s not the second and the third god. He is The One God in the sky and The One God in the earth. He is not twin god dan he doesn’t have a appeal. He say: قُلْ هُوَ اللَّهُ أَحَدٌ * اللَّهُ الصَّمَدُ * لَمْ يَلِدْ وَلَمْ يُولَدْ * وَلَمْ يَكُنْ لَهُ كُفُوًا أَحَدٌ * الأخلاص : 1- 4. Say (Muhammad) : He is Allah The One. Allah The Eternal, Absolute. He begets not, nor is He begotten. And there is none like unto Him.
