Imam Ali (AS) said, Indeed, if you crave after this world, you will waste your lives for that which you will not remain for and that which will not remain for you.
الإمامُ عليٌّ (عَلَيهِ الّسَلامُ) : إنَّكُمْ إنْ رَغِبْتُم فِي الدُّنْيا أفْنَيْتُمْ أعْمارَكُمْ فيما لا تَبْقُونَ لَهُ وَ لا يَبْقى لَكُمْ
