Slaves do not sacrifice. They only try and measure up. And they try to please the Master -- to the extent they can.
And of course many cheat like crazy.
As for me, I have no expectations of ever measuring up to what Allah wants from us or what we owe Allah.
The fact is there are two kinds of people in this world:
One, those whom Allah himself nudges and guides and pushes in the direction of working for him.
Two, those whom he turns away from working for him -- using all kinds of devices.
Then there is a third category: the Pretenders. The Munaafiqoon. They are neither here nor there.
And these groups are decided when they were still in the belly of their mother -- by Allah himself.
Take it how you want. But that is how it is.
