حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَنْبَأَنَا إِسْرَائِيلُ، عَنْ سِمَاكٍ، أَنَّهُ سَمِعَ مُوسَى بْنَ طَلْحَةَ، يُحَدِّثُ عَنْ أَبِيهِ
قَالَ مَرَرْتُ مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي نَخْلِ الْمَدِينَةِ فَرَأَى أَقْوَامًا فِي رُءُوسِ النَّخْلِ يُلَقِّحُونَ النَّخْلَ فَقَالَ: مَا يَصْنَعُ هَؤُلَاءِ قَالَ يَأْخُذُونَ مِنْ الذَّكَرِ فَيَحُطُّونَ فِي الْأُنْثَى يُلَقِّحُونَ بِهِ فَقَالَ: مَا أَظُنُّ ذَلِكَ يُغْنِي شَيْئًا فَبَلَغَهُمْ فَتَرَكُوهُ وَنَزَلُوا عَنْهَا فَلَمْ تَحْمِلْ تِلْكَ السَّنَةَ شَيْئًا فَبَلَغَ ذَلِكَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: إِنَّمَا هُوَ ظَنٌّ ظَنَنْتُهُ إِنْ كَانَ يُغْنِي شَيْئًا فَاصْنَعُوا فَإِنَّمَا أَنَا بَشَرٌ مِثْلُكُمْ وَالظَّنُّ يُخْطِئُ وَيُصِيبُ وَلَكِنْ مَا قُلْتُ لَكُمْ قَالَ اللَّهُ عَزَّ وَجَلَّ فَلَنْ أَكْذِبَ عَلَى اللَّهِ حَدَّثَنَا أَبُو النَّضْرِ حَدَّثَنَا إِسْرَائِيلُ حَدَّثَنَا سِمَاكُ بْنُ حَرْبٍ عَنْ مُوسَى بْنِ طَلْحَةَ فَذَكَرَهُ
I was with the Prophet (sallallahu alayhi wa sallam) and he passed by some palm trees of Madinah, and he saw some people at the top of the palm trees who were pollinating them.
He said: “What are these people doing?” said: “They are taking (pollen) from the male and putting it in the female, to fertilise it.” He said: ‘I do not think this can help in any way.’ News of that reached them, so they stopped doing that and came down from the trees, which did not bear any fruit that year as a result. News of that reached the Prophet (sallallahu alayhi wa sallam) and he said: “It was only a thought that crossed my mind.
If it helps in any way, then do it. I am only human, just like you, and thoughts may be right or wrong. But if I tell you that Allah, May He be glorified and exalted, said something, I will never tell a lie about Allah, may He be glorified and exalted.” It was narrated from Moosa ibn Talhah (and he narrated a similar report.) a similar report.
