إنَّ الدُّنيا كَالحَيَّةِ، لَيِّـنٌ مَسُّها، قاتِلٌ سَمُّها، فَأعْرِضْ عَمّا يُعْجِبُكَ فيها لِقِلَّةِ ما يَصْحَبُكَ مِنْها، وَ كُنْ آنَسَ ما تَكُونُ بِها أحْذَرَ ما تَكُونُ مِنْها
This world is like a snake: its skin is soft, but its venom is deadly. Therefore, avoid what you find attractive in it, because you will take little of it when you depart. And as much as it makes you happy, be vigilant.
