The Messenger of Allah ﷺ passed by some people who were at the top of the palm trees. He said: ʿWhat are these people doing?ʿ They said: “They are pollinating (the trees), putting the male with the female.” He said: ʿI do not think this can help in any way.” They were told about that and they stopped doing it. News of that reached the Messenger of Allah ﷺ and he said: “If it will benefit them, then let them do it. It was only a passing thought. Do not blame me for a mere thought, but if I tell you anything about Allah (may He be glorified and exalted) then accept it from me, for I will never tell a lie about Allah.ʿ
مَرَّ رَسُولُ اللهِ ﷺ عَلَى قَوْمٍ فِي رُءُوسِ النَّخْلِفَقَالَ مَا يَصْنَعُ هَؤُلاءِ؟ قَالُوا يُلَقِّحُونَهُ يَجْعَلُونَ الذَّكَرَ فِي الْأُنْثَى قَالَ مَا أَظُنُّ ذَلِكَ يُغْنِي شَيْئًا فَأُخْبِرُوا بِذَلِكَ فَتَرَكُوهُ فَأُخْبِرَ رَسُولُ اللهِ ﷺ فَقَالَ إِنْ كَانَ يَنْفَعُهُمْ فَلْيَصْنَعُوهُ فَإِنِّي إِنَّمَا ظَنَنْتُ ظَنًّا فَلا تُؤَاخِذُونِي بِالظَّنِّ وَلَكِنِ إذَا أَخْبَرْتُكُمْ عَنِ اللهِ ﷻ بِشَيْءٍ فَخُذُوهُ فَإِنِّي لَنِ أكْذِبَ عَلَى اللهِ شَيْئًا
