Is the god Allah supremepower and justice?

Answer 1

yes there is only Allah Almighty who have supreme and justice.

and quality of his justice is he count little details in justice ..

for more about his supreme and justice I strongly suggest you to read Quran in your local language translation that will help you alot.

take care ---- Bismillah a hadith says,

that on the Day of Judgement, Allah , Most Glorified, Most High,

will fold up the seven heavens and take them in His right Hand

and He will fold up the earth(or the whole creation) and take them in His other hand

and as He folds each of them,

He will call forth the tyrants and the arrogant people,

making them realise their insignificance by His Words:

"I am the King." - i.e. He is the true Owner of all things; He is Perfect in every respect and there is no weakness or defect in Him and that all those who claim kingship or sovereignty are in fact weak and feeble, powerless in His Grasp.

He will not be asked about what He does, but they will be asked.
