What would I feel if I was hungry and my friend told me like that?. ........ I don't know. But one thing that I know, I should not let myself die in hunger and entertain myself with "It's okay if I die in hunger because in heaven I can eat as much as I want".
Live the life is not always easy. There are many challenges and dificulties that we must face, like when we are seeking for a job, trying to find life-partner. Of course we should not easy to give up when face these dificulties. Unfortunatelly there are people who easy to give up and using pleasure in heaven as an excuse to give up, like "It's okay if I can't get what I want in this world, because later I will get it in heaven". I see this attitude in this forum too, and it made me wonder, if just want a worldly thing like being a movie actor, why must wait until die?. Why don't try make his own movie in this world?.
And the worse is, people like this also try to influence the others to give up. We can see the example in this forum. When someone tell his/her difficulty in getting married, instead of giving tips to make this person easier to get marrried, they suggest this person to give up with argument "Later in heaven you will get beautiful/handsome spouse".
Yes, the question in the opening post actually addressed tho people like this.
Using the pleasure in heaven as excuse to give up is not good, because it will make people lazy to do effort to make their life better.
This reminds me so much of an ayaa in the Quran. [36:47]
{And when it is said to them, "Spend from that which Allah has provided for you," those who disbelieve say to those who believe, "Should we feed one whom, if Allah had willed, He would have fed? You are not but in clear error."}
This, unfortunately, is the mentality of a significant amount of muslims around the world. They have a very morphed and incorrect understanding of fate and kada'a in islam (not saying im any better, but at least i know that you shouldnt entertain hunger and starvation with the idea and promise of heaven). And its not just them. Those who understand it well often fail to send the proper interpretation of it and focus too much about being patient and waiting for Allah's blessing to come raining down on them out of the blue without also stressing of the fact that we have to get off our butts and work it off till the blessings come. Its so heart breaking and gut wrenching to see those suffering get misled (even if its on accident) then feel betrayed about their religion.
These people often throw the word "sabr" and "patience" around like its the key to everything when its not. Its almost always a
temporary solution to calamities that afflict us, and rarely is it a
permanent one. Take for example the problem you mentioned about finding a spouse. Most people would rush to say "bare patience" and "InshAllah you will find one" or the dreaded "fear Allah" forgetting to also accompany them with useful and effective solutions to resolve the issue permanently. I dont know if this is because they automatically assume that you've tried all the solutions already and didnt work or what, but damn ... do they not understand that a person who is complaining can no longer use sabr as a solution? ... I mean, isnt it obvious that those who have been filled to the brim with sabr are the ones who often complain about their problems?
It gets to a point where i feel its all because these people detach themselves soo much from this dunya they are forgetting what it means to be human, what it means to feel needs of this dunya and how significate they are to the body, mind and even spirit. Its as if they are no longer human and act as if they are robots, pledging their entire life to a cause making themselves stripped of emotions and feelings to this dunya. Im not going to say that their cause is not noble (I believe that it is) but i do not think their methods is the best way to go around this. This way of life strips the person from empathy and the feeling of mercy towards others in this dunya. A path that leads to a dark and hollow heart, even if the cause is noble, is not a good path. One must maintain balance between his connection to both worlds but ultimately keeps in mind that his end destination is the hereafter. And this balance can never be achieved by stripping yourself from this dunya or the akhira (hereafter).
