Law of Attraction is claimed to be The way to achieve what ever you want in this life like money, relations, power etc.
Going through their literature, you can easily see that the claim is not totally practical although it is not completely empty. Allah (SWT) has created within us the power of intention which can make us achieve more than those who has no intention or weak intention. The strong intention makes us more able to come near to our goals, but it can not be absolute at all. The people who propagate for Law of Attraction, claim that you can fulfill all your wishes through Attraction including wealth, love, etc. You find many of them in practical life lacking what they propagate for.
We definitely believe in the power of intention, as we read the Hadeeth from Ima Jafar Al-Sadiq : No body is weak if his intention is strong ( ما ضعف بدن عن ما قويت عليه الإرادة). Nevertheless, we believe that it is not only our intention but our acts and help of Allah can make us achieve.
"Law of Attraction" fails to address or give proper attention the main factor in the universe, The Creator, Allah. Nothing can be achieved with out the help from Allah.
In short, this propaganda of Law of Attraction is run by non Muslims for non Muslims because they are away frm the treasures teachings and guidance that we have from Quran, the Prophet (SAWA) and Ahlul Bayt (AS).
