By looking at the Quranic teaching one can realise that God is the absolute truth. In Ayah 53 of Surah Fusselat, Allah (SWT) said: “they will be shown God’s signs in the furthest regions of the world and in their own souls until it becomes clear to them that this is the Truth. Is your God not enough as a witness for everything?” Of course Allah (SWT) shows Divine Signs to all but people must also use this opportunity and all the given tools to make this case clear for themselves and search for the absolute Truth.
Some people by tarnishing these given tools through committing sins and other mischiefs stop their heart and power of understanding to look for and recognising the absolute Truth as mentioned in Ayah 179 of Surah Al-A’araaf: “God created many Jinns and men for hell; they have hearts which cannot understand, eyes which cannot see and ears which cannot hear. They are like cattle, they are really misguided, and they are so heedless.”
