There is no objective morality without any reference to the transcendent. Good loses all meaning without reference to God. It becomes as in the west, where good just means 'what i like' and evil is 'what I don't like'. The ulema have said actions are morally neutral, they only become good or bad with reference to Allah's commands. You seem to be thinking that moral relativism is correct. It isn't. Plato spent a lot of effort refuting it, 2500 years ago. The fact is, people do think x is right and y is wrong, but they are wrong to think that unless is accords with allah's commands. Simple.
