most things are better and easier to be done earlier, but most people choose not to.
dirty dishes, for examples. you can either wash it straight away and avoid any unpleasant smells or tough stains that might be there over time. imagine the dishes are left until mould starts to appear.
another example that i'm sure most of us can identify with is our work, whether it's paper work or homework, or occupational work. leaving them to the last minute results in half-hearted works and imperfections in every aspects. not to mention the lack of sleep that oftenly accompany last-minute works, AKA the-work-that-is-done-on-the-day-before-the-deadline.
or our 5 times obligatory prayers. we do it early, we get more time to perform it properly, we get larger "pahala", and longer period of feeling at ease after doing our duty. but we tend to procrastinate till the the very end of the prayer time. sometimes even exceeds the time just to do other works, or sleep for that matter.
Hakikat agung disebalik surah Al-Asr:
وَالْعَصْرِ
إِنَّ الْإِنسَانَ لَفِي خُسْرٍ
إِلَّا الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ وَتَوَاصَوْا بِالْحَقِّ وَتَوَاصَوْا بِالصَّبْرِ
1. Demi Masa!
2. Sesungguhnya manusia itu dalam kerugian;
3. Kecuali orang-orang yang beriman dan beramal soleh dan mereka pula berpesan-pesan dengan kebenaran serta berpesan-pesan dengan sabar.
biarpun selanjut mana waktu pada seluruh zaman dan sepanjang mana kelangsungan hidup manusia pada semua masa, namun di sana hanya ada satu cara dan satu jalan hidup sahaja yang membawa keuntungan dan keselamatan. Itulah cara hidup yang telah dijelaskan sempadan-sempadan dan batu-batu tandanya dalam surah ini. Selain cara hidup ini adalah sia-sia dan rugi belaka. Wallahu'alam.
