Not in Islam it isn't.
The Prophet Muhammad (peace and blessing of God be upon him) said, "Actions depend on intentions." so if your intention is good and the action doesn't work out. Then you are rewarded for your good intention.
In fact there is another prophetic narration that states if a person has a bad intention and doesn't do the wrong action and leaves it. This is written as a good action!
So what about when someone does a good action - a Muslim is rewarded ten times what anyone else is and this increases with sincerity. And if this is doubled in Ramadan, like double points on your store card.
So, in Islam if your intentions are good there is reward and if your intentions are bad yet you don't do the wrong action then you are rewarded. So tell me where does a Muslim loose?
Your intentions are good and expect a reward. For a Muslim good intentions help you on the path to paradise.
