Short menbars - survival and Annihilation

The holy Quran says:

یَا قَوْمِ إِنَّمَا هَذِهِ الْحَیَاةُالدُّنْیَا مَتَاعٌ وَإِنَّ الْآخِرَةَ هِیَ دَارُ الْقَرَارِ

O My people! this life of the world Is but a passingenjoyment, and verily the Hereafter! that is the Abode of rest.

and also the commander of faithful pbuh says:

 أَیُّهَا النَّاسُ إِنَّا خُلِقْنَا وَ إِیَّاكُمْ لِلْبَقَاءِ لَالِلْفَنَاءِ لَكِنَّكُمْ مِنْ دَارٍ إِلَى دَارٍ تُنْقَلُونَ فَتَزَوَّدُوا لِمَاأَنْتُمْ‏ صَائِرُونَ‏ إِلَیْهِ‏ وَ خَالِدُونَ فِیه‏

O people! certainly we are created for survival, not forannihilation; this world is but a passage, while the next world is the place ofpermanent abode. therefore, take provisions from the passage (so much as youcan) for the way you are leading and the abode you will reside for good.

Imam Baqir pbuh says also in this regard:

 كَانَ أَمِیرُ الْمُؤْمِنِینَ ع بِالْكُوفَةِ إِذَا صَلَّىالْعِشَاءَ الْآخِرَةَ یُنَادِی النَّاسَ ثَلَاثَ مَرَّاتٍ حَتَّى یُسْمِعَ أَهْلَالْمَسْجِدِ أَیُّهَا النَّاس. اعْلَمُوا أَنَّ طَرِیقَكُمْ عَلَى الصِّرَاطِ وَالْهَوْلَ الْأَعْظَمَ أَمَامَكُمْ وَ عَلَى طَرِیقِكُمْ عَقَبَةٌ كَئُودٌ وَمَنَازِلُ‏ مَهُولَةٌ مَخُوفَةٌ لَا بُدَّ لَكُمْ مِنَ الْمَمَرِّ عَلَیْهَا وَالْوُقُوفِ بِهَا إِلَى الْمَعَادِ وَ مَمَرَّكُم

Imam Baqir: at themosque of al-Kufa, Imam Ali's practice was to address people three times aftereach instance of the night salat thus: O people! know that your way leads tothe hereafter and you will certainly pass through the path (al-Sirat), whileyou will experience great fear and frightening stations that are inevitable.
