One God – One Source are Muslims Deviating according to Allah?

Good question on Yahoo answers. My answer is as follows:

I think we need to separate between the dimension of IDEOLOGY and PRACTICE. Traditional Muslims have taken another source against the will of Allah as per the Quran. Have they DEVIATED? We can’t say that on the practical level although we believe so on the ideological level.

Traditional Muslims do good things as Roxie quoted 17/22-38. God will not let their efforts go to waste, inshaa Allah.
