These types of people whose understanding and awareness of the religion and the teachings of the school of thought are very simple and weak give excuses to the enemies (through these sorts of beliefs) that it is religion which causes the problems within the economy of a country. They make other people believe that it is religion itself which leads to a stopping of positive activity which could bring benefits to the (material) life of people.
These people think that it is religion which forces a person to submit his entire presence to such things (that could otherwise make them productive and well off) and makes them bring forth the excuse that if such and such gift were not granted to him, then for sure they would not have any sustenance reach them (and thus, they would have starved).
These types of people also think that if a particular sustenance was meant for them, then definitely without any questions it will reach them (and no one can stop it from coming to them). This sort of thought gives those who exploit others a very good opportunity to place the yolk of slavery around their necks and prevent them from the most basic of needs and requirements of life.
However, if these people possessed even a minute understanding of the Qur`an and the Islamic traditions, then it would be sufficient for them to reach the following conclusion that Islam requires a person to strive and struggle in order to acquire any sort of benefit in the material and spiritual realms of humanity.
We see that they were shepherds, tailors, cultivators of the fields and farmers. If the meaning that one's sustenance is guaranteed from Allah (SwT) means that we are to sit in our houses and wait for the sustenance to reach us, then we would not have seen the Prophets and A`immah - who were all much more acquainted and knowledgeable with the teachings of the religion than us - exerting such labour and toil in working!
