حَدَّثَنَا مَرْوَانُ بْنُ مُحَمَّدٍ ، حَدَّثَنَا رِفْدَةُ الْغَسَّانِيُّ ، حَدَّثَنَا ثَابِتُ بْنُ عَجْلَانَ الْأَنْصَارِيُّ ، قَالَ : كَانَ يُقَالُ :" إِنَّ اللَّهَ لَيُرِيدُ الْعَذَابَ بِأَهْلِ الْأَرْضِ، فَإِذَا سَمِعَ تَعْلِيمَ الصِّبْيَانِ الْحِكْمَةَ، صَرَفَ ذَلِكَ عَنْهُمْ ".
قَالَ مَرْوَانُ : يَعْنِي بِالْحِكْمَةِ : الْقُرْآنَ

Marwan bin Muhammad narrated to us, Rifdah Al-Ghassani narrated to us, Thabit bin Ajlan Al-Ansari narrated to us, he said: It was said: “Indeed, God wills Torment is befalling the people of the earth, so if he hears teaching children wisdom, that will be averted from them.”
Marwan said: What he means by wisdom is the Qur’an.
