انا اخلصناهم بخالصة ذكرى الدار

إِنَّآ أَخْلَصْنَـٰهُم بِخَالِصَةٍ ذِكْرَى ٱلدَّارِ

The purity of the inner self depends on how much you remember, desire, and think about the Hereafter. Allah says:

"Indeed, in the Messenger of Allah you have an excellent example for whoever has hope in Allah and the Last Day, and remembers Allah often." (33:21)

A few days ago, while I was having my meal during break time at work, there were three other co-workers on the same table who had already finished eating (because they started before me) and they were engaged in a casual conversation, and I was pretty much not saying anything at all and just listening to them. The discussion at one point centered around nostalgic feelings about their old experiences in their homeland, old memories, and the shared feelings that they had for their Bangladeshi cultural roots and how it's becoming harder to maintain that. They were speaking in my native language, but again, for some reason I wasn't able to situate myself into that discussion nor find it that interesting.

Later on, I started thinking that, even though such conversations are sometimes a good thing and it's a good way to spend time and socialize with others, it suggests that many of the things that people value so much and feel nostalgic for are kind of a possible sign of being heedless about the Hereafter. The culture, the memories, the "good old days," and even our relational ties will be completely forgotten on the Day of Resurrection, because those things won't matter anymore; then we will truly realize what has more value and importance in Allah's sight compared to the more worldly issues that people talk about.

In Surah Saad, verse 46, Allah tells us that Ibrahim, Isaac, and Yaqub (peace be upon them) were all chosen by Allah because of an exclusive and special quality - the remembrance of the Home (the Hereafter). Therefore, if this quality can be cultivated within ourselves, too, insha'Allah, then we will be more purified and our hearts will not get diverted by the noise and distractions around us.

وَٱذْكُرْ عِبَـٰدَنَآ إِبْرَٰهِيمَ وَإِسْحَـٰقَ وَيَعْقُوبَ أُو۟لِى ٱلْأَيْدِى وَٱلْأَبْصَـٰرِ ٭ إِنَّآ أَخْلَصْنَـٰهُم بِخَالِصَةٍ ذِكْرَى ٱلدَّارِ

"And remember Our servants - Ibrahim, Isaac, and Yaqub  - men of strength and insight. We truly chose them for the exclusive quality: the remembrance of the Home (the Hereafter)." (38:45-46)

Alhamdulillah. Jazak Allahu khayran. I am too struck by the fact that Allah(SWT) praises the quality of the remembrance of the hereafter. 
Thank you for sharing this, it has refreshed my perspective.
Just want to highlight in one of the places where translation is given instead of Yaqub(a.s.) Ayyub (a.s) is mentioned instead. Kindly check it.
Jazak Allahu khayran for the reflection!
