[Machine] I heard Abdullah ibn Busr saying, "Two Bedouins came to the Messenger of Allah ﷺ and one of them asked, 'O Messenger of Allah, who among the people is the best?' He said, 'The one whose life is long, and his deeds are good.' The other one asked, 'O Messenger of Allah, the rules and regulations of Islam have become abundant upon me. Command me with something that I can hold on to.' He said, 'Keep your tongue moist with the remembrance of Allah.'"  

أحمد:١٧٦٩٨ – حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ عَنْ مُعَاوِيَةَ يَعْنِي ابْنَ صَالِحٍ عَنْ عَمْرِو بْنِ قَيْسٍ قَالَ

سَمِعْتُ عَبْدَ اللهِ بْنَ بُسْرٍ يَقُولُ جَاءَ أَعْرَابِيَّانِ إِلَى رَسُولِ اللهِ ﷺ فَقَالَ أَحَدُهُمَا يَا رَسُولَ اللهِ أَيُّ النَّاسِ خَيْرٌ؟ قَالَ مَنْ طَالَ عُمْرُهُ وَحَسُنَ عَمَلُهُ وَقَالَ الْآخَرُ يَا رَسُولَ اللهِ إِنَّ شَرَائِعَ الْإِسْلَامِ قَدْ كَثُرَتْ عَلَيَّ فَمُرْنِي بِأَمْرٍ أَتَثَبَّتُ بِهِ فَقَالَ لَا يَزَالُلِسَانُكَ رَطْبًا مِنَ ذكر اللهِ

[Machine] The Prophet ﷺ was approached by two bedouins, and one of them asked him, "O Muhammad, who are the best of men?" The Prophet ﷺ replied, "The best of men are those who live a long life and perform good deeds." The other bedouin said, "We have been overwhelmed with numerous Islamic laws and regulations. Is there a way for us to hold onto something comprehensive?" The Prophet ﷺ replied, "Keep your tongue moist with the remembrance of Allah."

أَتَى النَّبِيَّ ﷺ أَعْرَابِيَّانِ فَقَالَ أَحَدُهُمَا مَنْ خَيْرُ الرِّجَالِ يَا مُحَمَّدُ؟ قَالَ النَّبِيُّ ﷺ مَنْ طَالَ عُمْرُهُ وَحَسُنَ عَمَلُهُ وَقَالَ الْآخَرُ إِنَّ شَرَائِعَ الْإِسْلَامِ قَدْ كَثُرَتْ عَلَيْنَا فَبَابٌ نَتَمَسَّكُ بِهِ جَامِعٌ؟ قَالَ لَا يَزَالُ لِسَانُكَ رَطْبًا مِنْ ذِكْرِ اللهِ
