Hadith on Knowledge: You know better the affairs of your world

Anas ibn Malik reported: The Messenger of Allah, peace and blessings be upon him, passed by people grafting trees. The Prophet said, “It would be better if you did not do that.” They abandoned the practice and there was a decline in the yield. The Prophet passed by again and said, “What is wrong with your trees?” They said, “You said not to do so.” The Prophet said, “You have better knowledge of the affairs of your world.

In another narration, the Prophet said, “If doing so would benefit them, then do so. Verily, I had an opinion, so do not blame me for my opinion. If I tell you something about Allah, adhere to it. I never lie about Allah Almighty.

عَنْ أَنَسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَرَّ بِقَوْمٍ يُلَقِّحُونَ فَقَالَ لَوْ لَمْ تَفْعَلُوا لَصَلُحَ قَالَ فَخَرَجَ شِيصًا فَمَرَّ بِهِمْ فَقَالَ مَا لِنَخْلِكُمْ قَالُوا قُلْتَ كَذَا وَكَذَا قَالَ أَنْتُمْ أَعْلَمُ بِأَمْرِ دُنْيَاكُمْ

وفي رواية أخرى قال إِنْ كَانَ يَنْفَعُهُمْ ذَلِكَ فَلْيَصْنَعُوهُ فَإِنِّي إِنَّمَا ظَنَنْتُ ظَنًّا فَلاَ تُؤَاخِذُونِي بِالظَّنِّ وَلَكِنْ إِذَا حَدَّثْتُكُمْ عَنِ اللَّهِ شَيْئًا فَخُذُوا بِهِ فَإِنِّي لَنْ أَكْذِبَ عَلَى اللَّهِ عَزَّ وَجَلَّ
