حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الرُّومِيِّ الْيَمَامِيُّ، وَعَبَّاسُ بْنُ عَبْدِ الْعَظِيمِ الْعَنْبَرِيُّ، وَأَحْمَدُ بْنُ، جَعْفَرٍ الْمَعْقِرِيُّ قَالُوا حَدَّثَنَا النَّضْرُ بْنُ مُحَمَّدٍ، حَدَّثَنَا عِكْرِمَةُ، - وَهُوَ ابْنُ عَمَّارٍ - حَدَّثَنَا أَبُو النَّجَاشِيِّ، حَدَّثَنِي رَافِعُ بْنُ خَدِيجٍ، قَالَ قَدِمَ نَبِيُّ اللَّهِ صلى الله عليه وسلم الْمَدِينَةَ وَهُمْ يَأْبُرُونَ النَّخْلَ يَقُولُونَ يُلَقِّحُونَ النَّخْلَ فَقَالَ ‏"‏ مَا تَصْنَعُونَ ‏"‏ ‏.‏ قَالُوا كُنَّا نَصْنَعُهُ قَالَ ‏"‏ لَعَلَّكُمْ لَوْ لَمْ تَفْعَلُوا كَانَ خَيْرًا ‏"‏ ‏.‏ فَتَرَكُوهُ فَنَفَضَتْ أَوْ فَنَقَصَتْ - قَالَ - فَذَكَرُوا ذَلِكَ لَهُ فَقَالَ ‏"‏ إِنَّمَا أَنَا بَشَرٌ إِذَا أَمَرْتُكُمْ بِشَىْءٍ مِنْ دِينِكُمْ فَخُذُوا بِهِ وَإِذَا أَمَرْتُكُمْ بِشَىْءٍ مِنْ رَأْىٍ فَإِنَّمَا أَنَا بَشَرٌ ‏"‏ ‏.‏ قَالَ عِكْرِمَةُ أَوْ نَحْوَ هَذَا ‏.‏ قَالَ الْمَعْقِرِيُّ فَنَفَضَتْ ‏.‏ وَلَمْ يَشُكَّ ‏.‏

Rafi' b. Khadij reported that Allah's Messenger (ﷺ) came to Medina and the people had been grafting the trees. He said: What are you doing? They said: We are grafting them, whereupon he said: It may perhaps be good for you if you do not do that, so they abandoned this practice (and the date-palms) began to yield less fruit. They made a mention of it (to the Holy Prophet), whereupon he said: I am a human being, so when I command you about a thing pertaining to religion, do accept it, and when I command you about a thing out of my personal opinion, keep it in mind that I am a human being. 'Ikrima reported that he said something like this.
