الدارمي:١٢٣ – أَخْبَرَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ حَدَّثَنَا حَمَّادُ بْنُ يَزِيدَ الْمِنْقَرِيُّ حَدَّثَنِي أَبِي قَالَ جَاءَ رَجُلٌ يَوْمًا إِلَى ابْنِ عُمَرَ فَسَأَلَهُ عَنْ شَيْءٍ لَا أَدْرِي مَا هُوَ فَقَالَ لَهُ ابْنُ عُمَرَ لَا تَسْأَلْ عَمَّا لَمْ يَكُنْ فَإِنِّي سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ رِضْوَانُ اللَّهِ عَلَيْهِ

يَلْعَنُ مَنْ سَأَلَ عَمَّا لَمْ يَكُنْ
