عَنْ أَبِي مُوسَى الْأَشْعَرِيِّ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ مَنْ أَحَبَّ دُنْيَاهُ أَضَرَّ بِآخِرَتِهِ وَمَنْ أَحَبَّ آخِرَتَهُ أَضَرَّ بِدُنْيَاهُ فَآثِرُوا مَا يَبْقَى عَلَى مَا يَفْنَى
It is narrated from Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) said: Whoever loves his worldly life will harm his Hereafter, and whoever prefers his Hereafter will harm his worldly life. So give preference to that which is everlasting over that which is perishable.
