The evidence of isbati al-tawhid according to Abu Muin al-Nasafi

One of the most important principle in the Islamic belief system brought to the human beings is the oneness of Allah (Tawhid). The world has been created by one God (Allah) so it has a single creator. This study examines that the creator of the universe is not many but one, both in terms of evidence and mental certainty. Therefore, Islamic theologians used the idea of "Burhân al-Tamânu" while proving that God is one and only (Ahad). Abu'l-Muin an-Nasafi also used the idea of "Tamânu" while proving the oneness of Allah (Tawhid). "Burhân al-Tamânu" means to hinder, to mutually prohibit each other from something. There are many verses that prove and explain the unity of God (Tawhid), but theologians generally use the following three verses while proving the unity of God with the proof of Burhân al-Tamânu. The main Islamic theologians who explain the issue with the proof of the oneness of Allah (Tawhid) are Imam-i Juveyni and Abul-Muin an-Nasafi. Scholars of Ahl al-Sunnah agree on this issue. Contrary to this, Mutezile does not see the evidence of burhan al-tamanu in the degree of certainty for explaining Allah. Some Islamic theologians saw this as persuasion, not as inference and reason.
