Surah Al-Isra (The Night Journey ) 17 : 19

• When the Akhirah is the only goal then all his affairs becomes focused but when it is the Dunyah then focus is shattered and splintered. The Prophet [saw]  is reported to have said, مَن كانتِ الآخرةُ هَمَّه . جعل اللهُ غِنَاه في قلبِه وجَمَع له شَمْلَه ، وأَتَتْه الدنيا وهي راغمةٌ ، ومَن كانت الدنيا هَمَّه . جعل اللهُ فقرَه بين عَيْنَيْهِ ، وفَرَّق عليه شَمْلَه ، ولم يَأْتِهِ من الدنيا إلا ما قُدِّرَ له "Whoever makes the Hereafter his worry, Allah makes his heart rich, and organizes his affairs, and the world comes to him whether it want to or not. And whoever makes the world his worry, Allah puts his poverty right before his eyes, and disorganizes his affairs, and the world does not come to him, except what has been decreed for him." [Sahih al-Jami]

Explanatory Note

On the other side is a totally different picture:

“But those who care only for the life to come, strive fir it as it should be striven for, and are true believers, are indeed the ones who will have their endeavours well rewarded.” (Verse 19)

Someone who desires the rich reward of the life to come must pursue his goal diligently. He should fulfil the duties God requires of him. Moreover, he must have faith which serves as the basis of his pursuit for the life to come. Faith is not a matter that people attain through idle wishes, but it is rather an idea that is firmly held as a belief, and clearly endorsed by action. Pursuit of the hereafter does not deprive anyone of the wholesome pleasures of this life. It simply opens up wider horizons before us. Thus, enjoyment and pleasure are not the driving goal. There is no harm in seeking pleasure, provided however that one is not captivated or enslaved by it.

A life that seeks nothing more than the pleasures of this world is fitting only for worms, reptiles, insects, cattle and wild beasts. It is only the life that pursues the rewards of the hereafter that is fitting for man who has been the recipient of honour bestowed on him by God. It is God who has created man and fashioned him, planting in his soul a secret that motivates him to look up to higher horizons even when his feet are solidly planted on earth.
