Hadith 7:45
‘Abdallah b. Busr told of a desert Arab coming to the Prophet and asking who was best among men, to which he replied, “Happy is he whose life is long and whose deeds are good.” He asked God’s messenger what deed was most excellent, and he replied, “That you should leave the world with the mention of God fresh on your tongue.” Ahmad and Tirmidhi transmitted it.
وَعَن عبد الله بن يسر قَالَ: جَاءَ أَعْرَابِيٌّ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: أَيُّ النَّاسِ خَيْرٌ؟ فَقَالَ: «طُوبَى لِمَنْ طَالَ عُمْرُهُ وَحَسُنَ عَمَلُهُ» قَالَ: يَا رَسُولَ اللَّهِ أَيُّ الْأَعْمَالِ أَفْضَلُ؟ قَالَ: ( «ن تُفَارِقَ الدُّنْيَا وَلِسَانُكَ رَطْبٌ مِنْ ذِكْرِ اللَّهِ» رَوَاهُ أَحْمد وَالتِّرْمِذِيّ
