وَقَالَ النَّبِيُّ ﷺ لَوْ أَنَّ النَّاسَ يَعْلَمُونَ مَا فِي النِّدَاءِ وَالصَّفِّ الأَوَّلِ ثُمَّ لَمْ يَجِدُوا إِلاَّ أَنْ يَسْتَهِمُوا عَلَيْهِ لاَسْتَهَمُوا عَلَيْهِ قَالَ حَدَّثَنَا بِذَلِكَ إِسْحَاقُ بْنُ مُوسَى الأَنْصَارِيُّ حَدَّثَنَا مَعْنٌ حَدَّثَنَا مَالِكٌ عَنْ سُمَىٍّ عَنْ أَبِي صَالِحٍ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ مِثْلَهُ
