Harmala ibn 'Abdullah went to the Prophet ﷺ and stayed with him until the Prophet ﷺ until the Prophet ﷺ recognised him. He said, "When we set out, I told myself, 'By Allah, I will go to the Prophet ﷺ so that I will have more knowledge. I went in the evening until I was in front of him. I asked, 'What do you command me to do?' He replied, 'Harmala, do what is correct and avoid the incorrect.' Then I went back to the caravan. Then I came back again until I was in my place near him. I asked, 'Messenger of Allah, what do you command me to do?' He replied, 'Harmala, do what is correct and avoid the incorrect. Find out what you like to hear people tell you when you are with them. When you leave me, behave in that manner. Find out what you dislike for people to day to you. When you leave me, avoid that.' When I returned, I thought that these two statements did not omit anything."

أَنَّهُ خَرَجَ حَتَّى أَتَى النَّبِيَّ ﷺ فَكَانَ عِنْدَهُ حَتَّى عَرَفَهُ النَّبِيُّ ﷺ فَلَمَّا ارْتَحَلَ قُلْتُ فِي نَفْسِي وَاللَّهِ لَآتِيَنَّ النَّبِيَّ ﷺ حَتَّى أَزْدَادَ مِنَ الْعِلْمِ فَجِئْتُ أَمْشِي حَتَّى قُمْتُ بَيْنَ يَدَيْهِ فَقُلْتُ مَا تَأْمُرُنِي أَعْمَلُ؟ قَالَ يَا حَرْمَلَةُ ائْتِ الْمَعْرُوفَ وَاجْتَنَبِ الْمُنْكَرَ ثُمَّ رَجَعْتُ حَتَّى جِئْتُ الرَّاحِلَةَ ثُمَّ أَقْبَلْتُ حَتَّى قُمْتُ مَقَامِي قَرِيبًا مِنْهُ فَقُلْتُ يَا رَسُولَ اللهِ مَا تَأْمُرُنِي أَعْمَلُ؟ قَالَ يَا حَرْمَلَةُ ائْتِ الْمَعْرُوفَ وَاجْتَنَبِ الْمُنْكَرَ وَانْظُرْ مَا يُعْجِبُ أُذُنَكَ أَنْ يَقُولَ لَكَ الْقَوْمُ إِذَا قُمْتَ مِنْ عِنْدِهِمْ فَأْتِهِ وَانْظُرِ الَّذِي تَكْرَهُ أَنْ يَقُولَ لَكَ الْقَوْمُ إِذَا قُمْتَ مِنْ عِنْدِهِمْ فَاجْتَنِبْهُ فَلَمَّا رَجَعْتُ تَفَكَّرْتُ فَإِذَا هُمَا لَمْ يَدَعَا شَيْئًا
