الإمام علي (عليه السَّلام):
إنَّ الدنيا وَ الآخِرَةَ عَدُوّانِ مُتَفاوِتانِ، وَ سَبيلانِ مُختَلِفانِ، فَمَن أحَبَّ الدنيا وَ تَولَاها أبغضَ الآخِرَةَ وَ عاداها، وَ هُما بِمَنزِلَةِ المَشرِقِ وَ المَغرِبِ وَ ماشٍ بَينَهُما كُلَّما قَرُبَ مِن واحدٍ بَعُدَ مِنَ الآخَرِ.
Imam Ali (as):
'Verily the world and the Hereafter are two opposing enemies and two different paths, so whoever loves and befriends the world has despised the Hereafter and has made it his enemy. They [the world and the Hereafter] are like the east and the west and whoever walks between them, however much he gets closer to one, he distances himself from the other. After all, they are like two wives of the same husband.'
