الترمذي:٢٦٩١ – حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ حَدَّثَنَا عُمَرُ بْنُ يُونُسَ حَدَّثَنَا عِكْرِمَةُ بْنُ عَمَّارٍ حَدَّثَنِي أَبُو زُمَيْلٍ حَدَّثَنِي ابْنُ عَبَّاسٍ حَدَّثَنِي عُمَرُ بْنُ الْخَطَّابِ قَالَ

اسْتَأْذَنْتُ عَلَى رَسُولِ اللَّهِ ﷺ ثَلاَثًا فَأَذِنَ لِي  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ وَأَبُو زُمَيْلٍ اسْمُهُ سِمَاكٌ الْحَنَفِيُّ وَإِنَّمَا أَنْكَرَ عُمَرُ عِنْدَنَا عَلَى أَبِي مُوسَى حَيْثُ رَوَى عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ الاِسْتِئْذَانُ ثَلاَثٌ فَإِنْ أُذِنَ لَكَ وَإِلاَّ فَارْجِعْ وَقَدْ كَانَ عُمَرُ اسْتَأْذَنَ عَلَى النَّبِيِّ ﷺ ثَلاَثًا فَأَذِنَ لَهُ وَلَمْ يَكُنْ عَلِمَ هَذَا الَّذِي رَوَاهُ أَبُو مُوسَى عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ فَإِنْ أُذِنَ لَكَ وَإِلاَّ فَارْجِعْ
