In the beginning of the Japanese Renaissance, the king of Japan sent seven students to Europe and America for study. They had been in an undeveloped country “Japan was undeveloped”, so when they went to great countries and cities they were distracted with the beautiful things therein so they went to their desires and failed. When they went back to Japan, the king executed them because they had forgotten the task they were sent for and got indulged in other things. Human being is sent to this world for a specific task. If he knows it and achieves it he would be happy in this world and in the Hereafter, but if he ignores it, doesn’t know it, or does something contrary to it, he would be so miserable when he dies that he screams badly:

“27. And (remember) the Day when the Zalim (wrong-doer, oppressor, polytheist, etc.) will bite at his hands, he will say: "Oh! Would that I had taken a path with the Messenger ( Muhammad).28. "Ah! Woe to me! Would that I had never taken so-and-so as a friend!29. "He indeed led me astray from the Reminder (this Qur'an) after it had come to me. And Shaitan (Satan) is ever a deserter to man in the hour of need."”

(Al-Furqan Surah)

 This is so serious. It shows you your responsibilities and tells you that you are created in this world to be prepared for eternal happiness, if you don’t you get eternal misery. You were created for happiness and came to this world to be prepared for the eternal happiness in a Heaven that is bigger than the heavens and earth. You accepted to carry the trust. You were brought to this world for a specific target, to be prepared for this eternal happiness, so one is distracted with money and life problems, another one achieves only limited earthly goals, and a third is distracted with nonsense. Some people spend their lives in disputes and nonsense. Allah says:

“1. By the night as it envelops;2. And by the day as it appears in brightness;3. And by Him Who created male and female;4. Certainly, your efforts and deeds are diverse (different in aims and purposes);”

(Al-Lail Surah)

 There is one right effort which is the effort to know Allah “the basis of religion is knowing Allah”. You are in this world for a serious task, so the believer is devoted to this task. If he wants to marry, he likes to marry a good woman because he is created for good deeds and the woman who is not good will destroy his spiritual life. You reject anything that would take all your time because you have a great task
