987. hadíth
وَ رُوِيَ عَنِ اَلْعَالِمِ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: "اِعْمَلْ لِدُنْيَاكَ كَأَنَّكَ تَعِيشُ أَبَداً وَ اِعْمَلْ لآِخِرَتِكَ كَأَنَّكَ تَمُوتُ غَداً".
It is narrated from the Imam (a.s) that he said: "Work for your worldly life as if you will live forever, and work for your Hereafter as if you will die tomorrow."
