Hadith 4:83
Abu Huraira reported God’s messenger as saying, “Keep much in your remembrance the cutter off of delights, i.e., death.” Tirmidhi, Nasa'i and Ibn Majah transmitted it.
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَكْثِرُوا ذِكْرَ هَاذِمِ اللَّذَّاتِ الْمَوْتِ» . رَوَاهُ التِّرْمِذِيُّ وَالنَّسَائِيّ وَابْن مَاجَه
