Tawhid is oneness of truth, as truth cannot be overruled by falsehood.
Truth: there is only One God.
Truth: there is only one Revelation of God left to humanity-Qur'an.
Truth: Creed of Abraham is when the signs of God show something, Qur'anic INTERPRETATION must be adjusted and not remain in the past.
Truth:human beings do not come from mother alone but require the mingling of 'fluid:
32:7 Who created everything in perfect balance. Thus He initiated the creation of the humans from hydrated inorganic matter.
32:8 Then He made him to be reproduced out of the essence of a mere fluid. [The inorganic matter was hydrated and life was initiated from its extract. Eventually, the evolution reached a point when procreation with male and female gametes was established. 37:11]
32:9 (Then emergent evolution took place that distinguished humans from the animal kingdom.) He shapes him in accordance with what he is meant to be, and breathes into him of His Energy. And thus (O Mankind) He gives you the faculties of hearing, sight, reasoning and feelings. Yet, how seldom are you grateful by making the best use of your perceptual and conceptual faculties! [Af’idah = Minds = Intellect = Faculty of reasoning including feelings. 17:36, 45:23, 46:26]
35:11 (Recall your common humble origin.) God created you from dust, then from male and female gametes, and then He makes you pairs. And no female becomes pregnant, nor gives birth without His knowledge (according to His appointed laws in nature, without exceptions). No one lives long, and no one lives short, but by His laws. All this is easy for God. [3:144. Nutfah = Gamete, male or female. Commonly misunderstood as sperm or semen, it is a common gender]
